1 00:00:00,320 --> 00:00:02,880 Speaker 1: Brought to you by the reinvented two thousand twelve camera. 2 00:00:03,200 --> 00:00:08,920 Speaker 1: It's ready. Are you get in touch with technology with 3 00:00:09,080 --> 00:00:17,840 Speaker 1: tech Stuff from how stuff works dot com. Hello again, everyone, 4 00:00:17,880 --> 00:00:20,040 Speaker 1: welcome to tech Stuff. My name is Chris Polette and 5 00:00:20,040 --> 00:00:22,320 Speaker 1: I am the tech editor at how stuff works dot com. 6 00:00:22,320 --> 00:00:25,360 Speaker 1: Sitting across from me as usual as senior writer Jonathan Strickling. Hey, 7 00:00:25,400 --> 00:00:29,760 Speaker 1: there is today. Actually, what are we going to talk about? Well, 8 00:00:29,800 --> 00:00:31,840 Speaker 1: today we're gonna talk about something that comes to us 9 00:00:31,920 --> 00:00:38,760 Speaker 1: courtesy of a little listener mail. This listener mail comes 10 00:00:38,760 --> 00:00:41,519 Speaker 1: from Jeff and Jeff says, Hey, Chris and Jonathan or 11 00:00:41,640 --> 00:00:44,920 Speaker 1: the unfortunate intern who must sift through listener mail first. 12 00:00:45,440 --> 00:00:49,680 Speaker 1: Uh no, Jeff, that's us. I am absolutely in love 13 00:00:49,720 --> 00:00:52,040 Speaker 1: with the podcast. I just finished listening to your show 14 00:00:52,120 --> 00:00:55,360 Speaker 1: on Hackintosh's and the unfortunate comment at the end of 15 00:00:55,360 --> 00:00:58,080 Speaker 1: the show about sticking with a PC if you want 16 00:00:58,120 --> 00:01:01,360 Speaker 1: to do the useful things. I love my Mac, but 17 00:01:01,440 --> 00:01:04,240 Speaker 1: I do have to agree I miss gaming too, which 18 00:01:04,280 --> 00:01:07,240 Speaker 1: is why I used Apple's boot camp to install Windows 19 00:01:07,319 --> 00:01:10,640 Speaker 1: XP on my Mac, resulting in a to the dual 20 00:01:10,760 --> 00:01:15,839 Speaker 1: boot system. A delusion. Questions is about to begin. How 21 00:01:16,000 --> 00:01:19,840 Speaker 1: the heck does it work. Boot Camp is provided by 22 00:01:19,959 --> 00:01:23,680 Speaker 1: Apple as if they're encouraging people to also install Windows 23 00:01:23,680 --> 00:01:26,440 Speaker 1: on their max. Of course, you still have to purchase 24 00:01:26,480 --> 00:01:29,120 Speaker 1: your own copy of Windows. Is that a violation of 25 00:01:29,120 --> 00:01:32,319 Speaker 1: the you love for either Apple or Microsoft? How or 26 00:01:32,400 --> 00:01:36,120 Speaker 1: why did Apple make their machines compatible with both operating systems? 27 00:01:36,440 --> 00:01:39,600 Speaker 1: And then how do other programs like Parallels, which allow 28 00:01:39,640 --> 00:01:42,560 Speaker 1: you to operate Windows while running your Mac work? Keep 29 00:01:42,640 --> 00:01:45,280 Speaker 1: up the great work. Jeff ps. A show on green 30 00:01:45,319 --> 00:01:48,120 Speaker 1: technology would be awesome too. I would not complain about that. 31 00:01:48,480 --> 00:01:52,279 Speaker 1: We're not doing a show on green technology. No. Today, 32 00:01:52,320 --> 00:01:56,920 Speaker 1: we're doing a show about multibooting. Yes, because your computer 33 00:01:57,040 --> 00:01:59,760 Speaker 1: will depending on your computer, but we'll get in a second. 34 00:01:59,760 --> 00:02:01,960 Speaker 1: Your Peter may or may not be able to run 35 00:02:02,080 --> 00:02:05,520 Speaker 1: multiple operating systems, not just you know, for example, Windows 36 00:02:05,520 --> 00:02:07,960 Speaker 1: and Mac. As you said, right, yeah, we when we're 37 00:02:07,960 --> 00:02:12,320 Speaker 1: talking about multibooting, it's uh, it's it's a wider net 38 00:02:12,360 --> 00:02:15,640 Speaker 1: than that. We're talking about things like a Lenox, Unix 39 00:02:15,720 --> 00:02:19,359 Speaker 1: things like that, not necessarily all of them at the 40 00:02:19,400 --> 00:02:21,280 Speaker 1: same time. Some of them work together and some of 41 00:02:21,320 --> 00:02:25,839 Speaker 1: them don't. Um And when we say work together, we'll 42 00:02:25,840 --> 00:02:27,560 Speaker 1: have to get into that a little bit. Too. It's 43 00:02:27,639 --> 00:02:30,480 Speaker 1: kind of, um, it's kind of an unusual situation. So 44 00:02:31,040 --> 00:02:33,959 Speaker 1: when you turn your computer on, right, and I'm talking 45 00:02:34,000 --> 00:02:35,720 Speaker 1: about like when you flip the power switch, and I'll 46 00:02:35,760 --> 00:02:37,520 Speaker 1: talk about when you buy it chocolates and say nice 47 00:02:37,560 --> 00:02:40,880 Speaker 1: things to it. Uh, there's a certain process that the 48 00:02:40,880 --> 00:02:44,320 Speaker 1: computer goes through in order to boot up. Now, this 49 00:02:44,360 --> 00:02:49,920 Speaker 1: process starts with the master boot record, Yes, which is 50 00:02:49,919 --> 00:02:53,040 Speaker 1: a sector at the very very beginning of the hard drive. Right, 51 00:02:53,360 --> 00:02:56,359 Speaker 1: so your your computer's hard drive, whatever format that might 52 00:02:56,400 --> 00:02:59,240 Speaker 1: be in. It could be a platter hard drive or 53 00:02:59,280 --> 00:03:02,520 Speaker 1: it could be so its state, but either way, within 54 00:03:02,600 --> 00:03:06,120 Speaker 1: that first sector, there's something called the master boot record. 55 00:03:06,160 --> 00:03:09,120 Speaker 1: Now this is this is the the little bit of 56 00:03:09,160 --> 00:03:14,160 Speaker 1: code that tells the essentially your computer where to go next, 57 00:03:14,840 --> 00:03:17,960 Speaker 1: like how how how to boot up the operating system. 58 00:03:18,000 --> 00:03:22,280 Speaker 1: So the uh, what I'll do is it'll it'll reference 59 00:03:22,360 --> 00:03:26,960 Speaker 1: a partition table and look for the active boot partition. 60 00:03:27,600 --> 00:03:31,080 Speaker 1: This is what then says, okay, well you know, if 61 00:03:31,120 --> 00:03:34,080 Speaker 1: we've passed go, here's the next square that we have 62 00:03:34,160 --> 00:03:37,360 Speaker 1: to move to. So it passes the control to the 63 00:03:37,400 --> 00:03:41,960 Speaker 1: partition boot record that continues the booting process. Now, the 64 00:03:42,040 --> 00:03:45,880 Speaker 1: partition boot record then looks for a system specific boot 65 00:03:45,920 --> 00:03:50,520 Speaker 1: files that are associated with that particular operating system. Right, 66 00:03:50,760 --> 00:03:53,200 Speaker 1: So the like a Windows that would start looking for 67 00:03:53,240 --> 00:03:57,520 Speaker 1: the I and I files. Um. At that point, it 68 00:03:57,600 --> 00:04:00,400 Speaker 1: then finishes the whole process of boot it ing, and 69 00:04:00,440 --> 00:04:03,480 Speaker 1: it loads up the operating system for your computer. Now, 70 00:04:03,520 --> 00:04:06,200 Speaker 1: if you only have one operating system on your computer, 71 00:04:06,280 --> 00:04:11,240 Speaker 1: this is a very straightforward process. It's just a straight shot, right. Yeah, 72 00:04:11,280 --> 00:04:15,920 Speaker 1: So NBR for the master boot record, NBR to the PBR, 73 00:04:16,760 --> 00:04:20,159 Speaker 1: which is not perhaps blue ribbon that several people listening 74 00:04:20,240 --> 00:04:23,359 Speaker 1: just thought that, Yeah, I know, um, but no, the 75 00:04:23,560 --> 00:04:26,320 Speaker 1: that's the the partition boot record, and then that goes 76 00:04:26,360 --> 00:04:30,840 Speaker 1: to the system files. So uh, pretty pretty straightforward. However, 77 00:04:31,600 --> 00:04:36,120 Speaker 1: the interesting thing about computers, or one interesting thing about computers, Yeah, 78 00:04:36,120 --> 00:04:38,800 Speaker 1: it turns out there's more than one. One of the 79 00:04:38,920 --> 00:04:41,640 Speaker 1: interesting things that you can learn about computers is that 80 00:04:41,720 --> 00:04:46,080 Speaker 1: you can install multiple operating systems on a computer if 81 00:04:46,160 --> 00:04:51,200 Speaker 1: you partition the hard drive correctly. That's true. Well, there 82 00:04:51,240 --> 00:04:54,760 Speaker 1: is an alternative. You could have multiple hard drives, each 83 00:04:54,839 --> 00:04:57,800 Speaker 1: with its own operating system. That's a little bit more 84 00:04:58,080 --> 00:05:00,719 Speaker 1: I should point out to Ouh. There's a lot of 85 00:05:00,760 --> 00:05:04,360 Speaker 1: detail that could go into a multiple boot system. So 86 00:05:04,440 --> 00:05:06,479 Speaker 1: we're not We're probably gonna take just a really high 87 00:05:06,600 --> 00:05:09,600 Speaker 1: end look at it, because we're talking about the the 88 00:05:09,600 --> 00:05:13,080 Speaker 1: basics here to see behind. As it turns out, depending 89 00:05:13,160 --> 00:05:16,200 Speaker 1: upon which operating systems you want to install, there are 90 00:05:16,200 --> 00:05:18,120 Speaker 1: a lot of different things you have to take into consideration. 91 00:05:18,240 --> 00:05:21,960 Speaker 1: For example, some versions of Windows can recognize when other 92 00:05:22,000 --> 00:05:25,520 Speaker 1: operating systems are installed on your computer, whether or not 93 00:05:25,640 --> 00:05:28,440 Speaker 1: that is the whether or not that that version of 94 00:05:28,480 --> 00:05:32,479 Speaker 1: Windows is your primary operating system. Some of them object 95 00:05:32,560 --> 00:05:35,560 Speaker 1: to not being the primary operating system, and if it's 96 00:05:35,600 --> 00:05:39,760 Speaker 1: not the primary, you're gonna have more headaches. You're gonna 97 00:05:39,839 --> 00:05:42,080 Speaker 1: there are ways of working around it, but you have 98 00:05:42,200 --> 00:05:46,000 Speaker 1: to find out what those ways are. Um, it's so, Yeah, 99 00:05:46,040 --> 00:05:48,160 Speaker 1: it can get really really complex, so we're gonna try 100 00:05:48,160 --> 00:05:50,840 Speaker 1: and keep it more general. In most cases, you can 101 00:05:50,880 --> 00:05:57,120 Speaker 1: find tools out there that make this fairly easy, or 102 00:05:57,160 --> 00:05:59,160 Speaker 1: at least easier than if you were to set out 103 00:05:59,160 --> 00:06:02,360 Speaker 1: and do it on your own. Yep, there's a so, 104 00:06:02,360 --> 00:06:05,200 Speaker 1: so it is possible. Getting back to what you were 105 00:06:05,200 --> 00:06:09,040 Speaker 1: saying before, Jonathan about um, you know they're being partitions 106 00:06:09,040 --> 00:06:11,680 Speaker 1: on a drive. You could have multiple drives with multiple 107 00:06:11,720 --> 00:06:15,560 Speaker 1: operating systems. But let's say you're you know, the average 108 00:06:15,600 --> 00:06:18,520 Speaker 1: person who is interested in a dual boot system, or 109 00:06:18,600 --> 00:06:21,479 Speaker 1: you know, in the case of our dear listener, someone 110 00:06:21,520 --> 00:06:25,000 Speaker 1: who has, uh, you know, the opportunity to install multiple 111 00:06:25,240 --> 00:06:29,320 Speaker 1: operating systems on one single hard disk. And in that case, yes, 112 00:06:29,360 --> 00:06:31,400 Speaker 1: you do want to partition your hard drive. And a 113 00:06:31,440 --> 00:06:35,000 Speaker 1: partition is pretty much exactly like what it sounds like. 114 00:06:35,040 --> 00:06:38,200 Speaker 1: It's it's a different part of your hard drive. Um. 115 00:06:38,240 --> 00:06:41,680 Speaker 1: And when you partition you're hard drive, you're basically telling, uh, 116 00:06:41,800 --> 00:06:44,800 Speaker 1: your computer, look, this part of the hard drive is 117 00:06:45,560 --> 00:06:50,440 Speaker 1: like its own hard drive. Your It's not literally a 118 00:06:50,440 --> 00:06:53,279 Speaker 1: different hard drive, but your computer treats it as though 119 00:06:53,279 --> 00:06:55,440 Speaker 1: it were a different hard drive. Right. So, if if 120 00:06:55,480 --> 00:06:58,080 Speaker 1: you want to think of it in physical terms, although 121 00:06:58,200 --> 00:07:03,000 Speaker 1: I should hasten to add that the physical representation is 122 00:07:03,000 --> 00:07:07,159 Speaker 1: is it's just an example. Um. The physical nature of 123 00:07:07,200 --> 00:07:10,440 Speaker 1: hard drives is also a very complicated thing. As it 124 00:07:10,480 --> 00:07:13,440 Speaker 1: turns out. You talk about cylinders and platters, and then 125 00:07:13,440 --> 00:07:16,080 Speaker 1: there's solid state drives, which are a different animal altogether, 126 00:07:16,480 --> 00:07:20,240 Speaker 1: and by animal, I mean hard drive. Don't write meat people, um. 127 00:07:20,400 --> 00:07:22,360 Speaker 1: But if you want to think of it in physical terms, 128 00:07:22,360 --> 00:07:25,360 Speaker 1: think of a room and you've got a pretty big room. No, 129 00:07:25,480 --> 00:07:28,800 Speaker 1: it's it's it's roomy in fact, and there's a you know, 130 00:07:28,920 --> 00:07:31,080 Speaker 1: it's a nice square room. And then you think, you 131 00:07:31,080 --> 00:07:32,960 Speaker 1: know what, I want to set this one corner of 132 00:07:32,960 --> 00:07:36,640 Speaker 1: the room off to be a room where I store 133 00:07:36,680 --> 00:07:38,680 Speaker 1: all my stuff. It's gonna be essentially a closet. So 134 00:07:38,680 --> 00:07:42,480 Speaker 1: you build a couple of walls, um, and you you 135 00:07:42,480 --> 00:07:45,480 Speaker 1: you partition off that room. There's still a door into 136 00:07:45,480 --> 00:07:47,760 Speaker 1: the big room, so you can get back and forth, 137 00:07:48,240 --> 00:07:51,440 Speaker 1: but it's set aside. And then you think, hey, you 138 00:07:51,480 --> 00:07:53,520 Speaker 1: know what, I've got that place to store my stuff. 139 00:07:53,520 --> 00:07:55,600 Speaker 1: But I really want I want I want a special 140 00:07:55,920 --> 00:07:59,400 Speaker 1: corner here so I can watch movies and play video 141 00:07:59,400 --> 00:08:02,200 Speaker 1: games and stuff. So I'm gonna build another wall and uh, 142 00:08:02,200 --> 00:08:04,840 Speaker 1: and I'm going to corner off this section here from 143 00:08:04,880 --> 00:08:07,720 Speaker 1: the main part of the room. Well, that's essentially what 144 00:08:07,720 --> 00:08:09,880 Speaker 1: you're doing. When you're partitioning off a hard drive. You 145 00:08:09,920 --> 00:08:13,360 Speaker 1: are taking up the whole and you're dividing it up 146 00:08:13,400 --> 00:08:16,960 Speaker 1: into parts. Um. These parts, of course have to be 147 00:08:17,000 --> 00:08:19,960 Speaker 1: smaller than the whole. We can't magically make our hard 148 00:08:20,040 --> 00:08:23,160 Speaker 1: drives larger than what they were before. Uh. And in fact, 149 00:08:23,240 --> 00:08:26,280 Speaker 1: this caused some issues back when hard drives started to 150 00:08:26,760 --> 00:08:30,080 Speaker 1: bump up against the eight gigabyte range, because before that 151 00:08:30,240 --> 00:08:34,000 Speaker 1: there was a physical limit based upon the hard drive 152 00:08:34,080 --> 00:08:37,000 Speaker 1: architecture that a gigabytes. That was that was as high 153 00:08:37,000 --> 00:08:39,200 Speaker 1: as you were gonna go. And we got around that, 154 00:08:39,400 --> 00:08:43,800 Speaker 1: but almost like by tricking the computer um at any rate, 155 00:08:43,840 --> 00:08:46,800 Speaker 1: So you can partition off your hard drive that way. 156 00:08:47,760 --> 00:08:50,080 Speaker 1: If you wanted to install more than one operating system 157 00:08:50,120 --> 00:08:52,880 Speaker 1: on your computer, you would need to have a partition, 158 00:08:52,920 --> 00:08:56,720 Speaker 1: at least a partition per operating system. So if you 159 00:08:56,760 --> 00:08:59,240 Speaker 1: had to operating systems, you would need at the very 160 00:08:59,320 --> 00:09:02,719 Speaker 1: least you partitions. You may want to do more than that. 161 00:09:02,800 --> 00:09:05,920 Speaker 1: You may want both operating systems to have access to 162 00:09:06,000 --> 00:09:08,800 Speaker 1: the same data. For example, let's say that you have 163 00:09:09,120 --> 00:09:11,200 Speaker 1: two different versions of Windows that you want to run 164 00:09:11,320 --> 00:09:13,480 Speaker 1: and and there may be reasons why you would need 165 00:09:13,520 --> 00:09:15,600 Speaker 1: to do this, and we'll get into that in a 166 00:09:15,640 --> 00:09:18,480 Speaker 1: little bit, but if you had these two different versions 167 00:09:18,520 --> 00:09:20,160 Speaker 1: of Windows, but you want to be able to access 168 00:09:20,160 --> 00:09:23,400 Speaker 1: the same general data, you would need a third partition 169 00:09:23,440 --> 00:09:25,560 Speaker 1: that would hold all the data, and both of your 170 00:09:25,640 --> 00:09:28,880 Speaker 1: operating systems would have to be able to access that partition. 171 00:09:30,400 --> 00:09:35,880 Speaker 1: While maintaining separation between the two operating system partitions and 172 00:09:35,920 --> 00:09:42,080 Speaker 1: the flowers are still standing. Yes. Nice, that's a ghostbuster's reference. Um. 173 00:09:42,080 --> 00:09:44,880 Speaker 1: It took me a second to put it together. But yeah. 174 00:09:44,920 --> 00:09:49,240 Speaker 1: So let's say that you've partitioned your hard drive. Would 175 00:09:49,280 --> 00:09:51,000 Speaker 1: there are many tools out there that allow you to 176 00:09:51,000 --> 00:09:53,880 Speaker 1: do this. By the way, before you partition anything, before 177 00:09:53,920 --> 00:09:58,439 Speaker 1: you ever try this, back up your hard hard drive, 178 00:09:59,000 --> 00:10:02,760 Speaker 1: and I'll tell you it's it's um, it's a good idea. Actually. 179 00:10:02,800 --> 00:10:06,040 Speaker 1: I read people who are you know, who are writing 180 00:10:06,520 --> 00:10:10,240 Speaker 1: tutorials on how to create a multi boot system or 181 00:10:10,280 --> 00:10:12,040 Speaker 1: to partition or hard drives, and one of the first 182 00:10:12,080 --> 00:10:14,280 Speaker 1: things that they say, other than back up your hard drive, 183 00:10:14,400 --> 00:10:16,480 Speaker 1: is maybe you don't necessarily want to do this with 184 00:10:16,520 --> 00:10:19,080 Speaker 1: your main computer. Yeah. Yeah, I would avoid doing this 185 00:10:19,120 --> 00:10:21,319 Speaker 1: with your main computer. If you have a secondary computer, 186 00:10:21,640 --> 00:10:23,640 Speaker 1: that would be all right for you to play with. 187 00:10:23,679 --> 00:10:27,040 Speaker 1: But um, there are problems that can come up from 188 00:10:27,120 --> 00:10:30,040 Speaker 1: partitioning your hard drive if things, especially depending on the 189 00:10:30,040 --> 00:10:35,120 Speaker 1: the combination of operating systems you've chosen. Um, and don't 190 00:10:35,120 --> 00:10:37,160 Speaker 1: just do it willy nilly. I mean, if you're willing 191 00:10:37,200 --> 00:10:39,960 Speaker 1: to accept the risk, you know, go right ahead. But 192 00:10:40,360 --> 00:10:42,120 Speaker 1: just keep in mind that there is a possibility that 193 00:10:42,559 --> 00:10:45,359 Speaker 1: you could, um, you could erase a lot of information 194 00:10:46,160 --> 00:10:49,160 Speaker 1: right that term paper that you have do on Friday, 195 00:10:49,200 --> 00:10:52,200 Speaker 1: that you just got your second draft done and oh 196 00:10:52,320 --> 00:10:56,920 Speaker 1: don it now it's gone. Yeah. Um. And keep in 197 00:10:57,000 --> 00:11:00,400 Speaker 1: mind also that operating systems can have is uose with 198 00:11:00,520 --> 00:11:04,520 Speaker 1: different parts of your hardware. Um. Things that work fine 199 00:11:04,559 --> 00:11:07,440 Speaker 1: in one operating system may stop working in another because 200 00:11:07,480 --> 00:11:10,640 Speaker 1: the drivers aren't there. That's true, you should um. Not 201 00:11:10,760 --> 00:11:14,880 Speaker 1: all operating systems are are created equal. As a matter 202 00:11:14,920 --> 00:11:18,800 Speaker 1: of fact, This answers one of one of the questions. UM, 203 00:11:18,840 --> 00:11:23,320 Speaker 1: because we were talking about what enables a Mac to 204 00:11:23,360 --> 00:11:25,920 Speaker 1: do this now when you couldn't do it before. Okay, 205 00:11:25,960 --> 00:11:29,800 Speaker 1: so before um, when they were running these power PC chips, Uh, 206 00:11:29,920 --> 00:11:33,760 Speaker 1: the operating system for Windows would just not run on it. 207 00:11:34,080 --> 00:11:36,040 Speaker 1: So you were you had to make a choice if 208 00:11:36,040 --> 00:11:39,400 Speaker 1: you wanted to buy a Mac, you ran the Mac os. UM. Well, 209 00:11:39,480 --> 00:11:42,480 Speaker 1: when Apple decided to change course and switched over to 210 00:11:42,880 --> 00:11:46,200 Speaker 1: Intel chips, Um, they are essentially the same chips that 211 00:11:46,240 --> 00:11:48,920 Speaker 1: go inside a PC. Actually they are the same chips 212 00:11:48,920 --> 00:11:53,000 Speaker 1: because they will run Windows. UM and uh. And yes, 213 00:11:53,040 --> 00:11:55,520 Speaker 1: to answer the other question, Apple is okay with you 214 00:11:55,679 --> 00:11:58,800 Speaker 1: UH using bootcamp to partition your hard drive and install 215 00:11:58,840 --> 00:12:00,520 Speaker 1: a copy of Windows on there. And of fact, it's 216 00:12:00,520 --> 00:12:04,680 Speaker 1: a selling point for them right right because before you 217 00:12:04,720 --> 00:12:06,920 Speaker 1: know you you it was a macor a PC. Now 218 00:12:06,920 --> 00:12:09,280 Speaker 1: you can do both, and that makes the Mac more 219 00:12:09,360 --> 00:12:11,839 Speaker 1: valuable to some people because they can run programs from 220 00:12:11,880 --> 00:12:14,440 Speaker 1: with operating Because what's interesting is you can't do it 221 00:12:14,520 --> 00:12:17,040 Speaker 1: the other way around, or at least Apple doesn't want 222 00:12:17,080 --> 00:12:18,760 Speaker 1: you to. You can do it, but in order for 223 00:12:18,800 --> 00:12:20,640 Speaker 1: you to be able to run the mac os on 224 00:12:20,679 --> 00:12:25,480 Speaker 1: a PC, you have to essentially fool the operating system 225 00:12:25,480 --> 00:12:28,440 Speaker 1: into believing it is on a Mac. Yeah, it would 226 00:12:28,440 --> 00:12:30,960 Speaker 1: have to. UM, the Mac is going to have to 227 00:12:31,000 --> 00:12:35,520 Speaker 1: recognize the components inside the machine, and if it looks 228 00:12:35,640 --> 00:12:38,480 Speaker 1: like it isn't Mac, it's not going to want to 229 00:12:38,559 --> 00:12:41,200 Speaker 1: run on it. Yeah. Now, again, you can fool the 230 00:12:41,240 --> 00:12:44,600 Speaker 1: operating system using various kinds of software in order to 231 00:12:44,800 --> 00:12:47,000 Speaker 1: UH to force it to run on a PC. But 232 00:12:47,080 --> 00:12:50,120 Speaker 1: your mileage may vary as far as how reliable it goes. 233 00:12:50,559 --> 00:12:53,719 Speaker 1: So getting back to to the whole multibooting concept here. 234 00:12:53,840 --> 00:12:57,120 Speaker 1: Now we've partitioned our hard drive UM several times, we 235 00:12:57,200 --> 00:12:59,360 Speaker 1: know that it's going to work on that computer. Right. Yeah, Well, 236 00:12:59,440 --> 00:13:02,600 Speaker 1: let's let's assume that we have already taken into account 237 00:13:02,600 --> 00:13:04,920 Speaker 1: the different operating systems we're going to use. Let's go 238 00:13:04,960 --> 00:13:07,800 Speaker 1: ahead and say we're running, um, two different versions of 239 00:13:07,800 --> 00:13:09,800 Speaker 1: Windows and a version of Linux. So we have three 240 00:13:09,800 --> 00:13:13,160 Speaker 1: different operating systems on this one machine. We've got let's 241 00:13:13,200 --> 00:13:17,120 Speaker 1: say five partitions total. All right, So each partition for 242 00:13:17,120 --> 00:13:20,000 Speaker 1: the operating system you've you've created it so it's just 243 00:13:20,160 --> 00:13:24,000 Speaker 1: big enough to hold that operating system, all right, So 244 00:13:24,080 --> 00:13:26,440 Speaker 1: that means that but you could do it, But you 245 00:13:26,440 --> 00:13:28,960 Speaker 1: could do you could do it where each each one 246 00:13:29,120 --> 00:13:31,560 Speaker 1: is maybe give it a little room, but more or less, 247 00:13:31,600 --> 00:13:34,560 Speaker 1: what you've got is a partition that's large enough to 248 00:13:34,720 --> 00:13:38,440 Speaker 1: hold each operating system. And then you've dedicated the rest 249 00:13:38,440 --> 00:13:41,240 Speaker 1: of your space for storage right in your in your 250 00:13:41,240 --> 00:13:45,560 Speaker 1: two different drives that you're using for storage. Now, um, 251 00:13:45,600 --> 00:13:49,360 Speaker 1: when you boot up the computer, depending on how you 252 00:13:49,400 --> 00:13:54,440 Speaker 1: set up the master boot record, because this this different 253 00:13:54,679 --> 00:13:58,400 Speaker 1: vendors do different methods. Actually Microsoft is very different from 254 00:13:58,480 --> 00:14:01,280 Speaker 1: everyone else. But if you were to uh, for the 255 00:14:01,320 --> 00:14:03,600 Speaker 1: most part, what happens is when you boot up, the 256 00:14:03,679 --> 00:14:06,600 Speaker 1: first step is the same. The master boot record looks 257 00:14:06,720 --> 00:14:10,320 Speaker 1: at the partition table, only this time there are choices. 258 00:14:10,880 --> 00:14:13,560 Speaker 1: It is no longer, oh, I need to hand over 259 00:14:13,640 --> 00:14:18,480 Speaker 1: the booting power to this very particular uh PBR again 260 00:14:18,600 --> 00:14:23,320 Speaker 1: not perhaps blue ribbon, the partition boot record. I can't 261 00:14:23,400 --> 00:14:25,880 Speaker 1: just do that because there are multiple choices. And then 262 00:14:26,920 --> 00:14:29,040 Speaker 1: what will happen is you'll be presented with the choice 263 00:14:29,080 --> 00:14:33,440 Speaker 1: of which operating system you wish to boot into, right, 264 00:14:33,600 --> 00:14:35,920 Speaker 1: and so you choose that one, and then the rest 265 00:14:35,920 --> 00:14:38,520 Speaker 1: of the process pretty much is the same. So the 266 00:14:38,520 --> 00:14:42,720 Speaker 1: the NBR will hand over the booting to the PBR, 267 00:14:42,840 --> 00:14:46,880 Speaker 1: which then moves forward from there and and accesses the 268 00:14:46,960 --> 00:14:50,880 Speaker 1: appropriate system specific boot files in order to to start 269 00:14:50,920 --> 00:14:53,520 Speaker 1: up the operating system. So with Linux, it's going to 270 00:14:53,600 --> 00:14:56,920 Speaker 1: be one set. With whatever version of Windows you're running, 271 00:14:56,920 --> 00:14:58,840 Speaker 1: it's going to be another set. And then of course 272 00:14:58,880 --> 00:15:01,560 Speaker 1: your your second version of Windows will use yet a 273 00:15:01,640 --> 00:15:05,040 Speaker 1: third set, so um you could choose any of those three. 274 00:15:05,360 --> 00:15:09,320 Speaker 1: You have to remember that this is divvying up your 275 00:15:09,320 --> 00:15:11,960 Speaker 1: computer's resources, so your computer is not gonna have nearly 276 00:15:12,000 --> 00:15:14,600 Speaker 1: the amount of storage space that used to have. UM 277 00:15:14,680 --> 00:15:17,160 Speaker 1: it can also depending on the operating systems you've chosen, 278 00:15:17,160 --> 00:15:21,000 Speaker 1: it can affect performance in other ways. Um, it could 279 00:15:21,120 --> 00:15:24,720 Speaker 1: make your computer run a little more slowly. Uh. Depending 280 00:15:24,720 --> 00:15:26,920 Speaker 1: on how you've partitioned the drives, it may have more 281 00:15:26,960 --> 00:15:30,080 Speaker 1: trouble accessing the hard drive in order to find the 282 00:15:30,160 --> 00:15:33,320 Speaker 1: right information it needs to operate. Um. It's a tricky thing, 283 00:15:33,640 --> 00:15:36,400 Speaker 1: which is again another reason why it's a good idea 284 00:15:36,400 --> 00:15:38,320 Speaker 1: to use this on a secondary or or you know, 285 00:15:38,360 --> 00:15:40,800 Speaker 1: even a tertiary machine or whatever. You know, some spare 286 00:15:40,840 --> 00:15:43,960 Speaker 1: machine you have as opposed to your primary one, just 287 00:15:44,040 --> 00:15:48,000 Speaker 1: because if stuff goes wrong, then you haven't lost all. 288 00:15:48,680 --> 00:15:51,480 Speaker 1: You haven't lost your your primary machine. Yeah, if you're already, 289 00:15:51,480 --> 00:15:54,560 Speaker 1: If you're partitioning machine, that's I'm sorry. If you're partitioning 290 00:15:54,560 --> 00:15:58,160 Speaker 1: a hard drive on a machine that has uh um 291 00:15:58,400 --> 00:16:01,960 Speaker 1: been formatted. Say you have a a Windows XP machine 292 00:16:02,600 --> 00:16:06,200 Speaker 1: with a five gigabyte hard drive, and you've had this 293 00:16:06,240 --> 00:16:08,080 Speaker 1: machine for two years now, and you say, you know what, 294 00:16:08,240 --> 00:16:11,000 Speaker 1: I'm ready to try Linux. I want to install Linux 295 00:16:11,040 --> 00:16:15,240 Speaker 1: on here. I want to partition my hard drive. Well, UM, 296 00:16:15,320 --> 00:16:18,480 Speaker 1: you're gonna have to sort of be very careful because 297 00:16:19,320 --> 00:16:22,240 Speaker 1: the information on there. You know, of course, you probably 298 00:16:22,280 --> 00:16:25,680 Speaker 1: know about defragmentation, how data can get stored in different 299 00:16:25,680 --> 00:16:28,280 Speaker 1: sectors on a hard drive, all over the hard drive. 300 00:16:28,320 --> 00:16:30,840 Speaker 1: But what a partition is gonna want to do the 301 00:16:31,000 --> 00:16:34,480 Speaker 1: partitioning tool, it's gonna want to create a part of 302 00:16:34,520 --> 00:16:36,800 Speaker 1: the hard drive that doesn't have any information on it. 303 00:16:37,160 --> 00:16:39,680 Speaker 1: And so you know, you have to try to judge 304 00:16:39,720 --> 00:16:43,400 Speaker 1: how much room you want to save on the Windows partition, like, well, 305 00:16:43,400 --> 00:16:45,160 Speaker 1: how much am I gonna how much space am I 306 00:16:45,200 --> 00:16:46,880 Speaker 1: gonna need on there? How much? You know, am I 307 00:16:46,920 --> 00:16:48,680 Speaker 1: going to run the risk? And it warns you if 308 00:16:49,160 --> 00:16:52,280 Speaker 1: when I installed UM it won't two on our test 309 00:16:52,320 --> 00:16:54,360 Speaker 1: machine here in the office. It warned you. It says, 310 00:16:54,480 --> 00:16:56,640 Speaker 1: you know, look, there is a possibility that some of 311 00:16:56,640 --> 00:16:59,360 Speaker 1: your files could be damaged in this process because it's 312 00:16:59,400 --> 00:17:01,320 Speaker 1: already formed at it And are you sure you really 313 00:17:01,360 --> 00:17:03,480 Speaker 1: want to do this? And I'm sure it's just a precaution, 314 00:17:04,200 --> 00:17:07,159 Speaker 1: but so you know, just be aware that formatting a 315 00:17:07,200 --> 00:17:08,680 Speaker 1: hard you know, that's why we were sort of talking 316 00:17:08,680 --> 00:17:11,680 Speaker 1: about the idea of starting from scratch, you know, brand 317 00:17:11,720 --> 00:17:13,720 Speaker 1: new hard drive. Let's go ahead and throw three different 318 00:17:13,720 --> 00:17:16,199 Speaker 1: operating systems on there. You know, if you're doing this 319 00:17:16,280 --> 00:17:19,399 Speaker 1: with a hard drive with an operating system that's been 320 00:17:19,440 --> 00:17:21,720 Speaker 1: on there for a while, you know that information is 321 00:17:21,720 --> 00:17:22,959 Speaker 1: going to be spread out a little bit, you might 322 00:17:22,960 --> 00:17:25,200 Speaker 1: want to run a defragment or on it and clean 323 00:17:25,280 --> 00:17:27,520 Speaker 1: up to drive a good bit before you partitioning. Yeah, 324 00:17:27,520 --> 00:17:29,880 Speaker 1: if you don't, if you don't mind the idea of 325 00:17:30,320 --> 00:17:33,520 Speaker 1: totally wiping your computer and starting from scratch, then that 326 00:17:33,520 --> 00:17:36,520 Speaker 1: that solves a lot of problems. But as we as 327 00:17:36,680 --> 00:17:39,520 Speaker 1: we mentioned Chris, that was a really good point because, 328 00:17:39,560 --> 00:17:42,960 Speaker 1: like I said before, with the physical representation that room, 329 00:17:43,000 --> 00:17:46,840 Speaker 1: where you you easily block off a corner here, in 330 00:17:46,840 --> 00:17:49,040 Speaker 1: a corner there, that's not the way it really works 331 00:17:49,080 --> 00:17:51,159 Speaker 1: on a computer. On a computer, you could think of 332 00:17:51,160 --> 00:17:54,160 Speaker 1: it as a high rise building with lots and lots 333 00:17:54,200 --> 00:17:57,480 Speaker 1: of different rooms, and certain rooms have their lights on, 334 00:17:57,560 --> 00:17:59,359 Speaker 1: and other rooms have the lights off, and the rooms 335 00:17:59,359 --> 00:18:01,359 Speaker 1: that the lights off, those are those are free. You 336 00:18:01,359 --> 00:18:04,000 Speaker 1: can use those too put in more information. But they're 337 00:18:04,040 --> 00:18:07,439 Speaker 1: scattered all across the building in different levels, and and 338 00:18:07,560 --> 00:18:09,919 Speaker 1: some levels have almost all the lights off, and some 339 00:18:10,000 --> 00:18:11,920 Speaker 1: levels have almost all the lights on, and others are 340 00:18:11,960 --> 00:18:14,920 Speaker 1: are kind of a jumble. Um. That's why it's kind 341 00:18:14,960 --> 00:18:18,680 Speaker 1: of that this can get really complicated because to partition off, 342 00:18:18,720 --> 00:18:21,360 Speaker 1: say all right, well, I need a block of sixty 343 00:18:21,480 --> 00:18:24,639 Speaker 1: rooms that have no lights on. Uh, there may not 344 00:18:24,720 --> 00:18:28,200 Speaker 1: be an adjacent block of sixty and may be spread across. 345 00:18:28,240 --> 00:18:30,680 Speaker 1: So again we're talking about a difference between the physical 346 00:18:30,760 --> 00:18:34,040 Speaker 1: structure of the hard drive and what the actual digital 347 00:18:34,080 --> 00:18:37,600 Speaker 1: representation is. Which is why the more I read about this, 348 00:18:37,880 --> 00:18:43,640 Speaker 1: the more my head hurts, because I was an English major. Well, thankfully, 349 00:18:44,119 --> 00:18:47,679 Speaker 1: most of the utilities now for the most modern operating 350 00:18:47,680 --> 00:18:49,560 Speaker 1: systems that will help you with this. You know, things 351 00:18:49,560 --> 00:18:53,600 Speaker 1: like g parted, which is a a free, open source 352 00:18:54,200 --> 00:18:58,280 Speaker 1: UM utility UM and of course boot camp for the Mac. 353 00:18:58,440 --> 00:18:59,960 Speaker 1: They'll help you through it. They'll walk you through it. 354 00:19:00,080 --> 00:19:02,960 Speaker 1: If you're installing UM, I know most flavors of Linux 355 00:19:03,560 --> 00:19:05,919 Speaker 1: have you know, when you're installing the computer it it 356 00:19:06,040 --> 00:19:08,240 Speaker 1: helps you walk you through the process of doing this. 357 00:19:08,359 --> 00:19:10,359 Speaker 1: Do you really want to partition your hard drive? You 358 00:19:10,359 --> 00:19:12,960 Speaker 1: can that way you can install you know this along 359 00:19:13,000 --> 00:19:15,040 Speaker 1: with your normal operating system or would you prefer just 360 00:19:15,080 --> 00:19:18,680 Speaker 1: to wipe the whole thing clean? Um? So, thankfully it 361 00:19:19,000 --> 00:19:21,520 Speaker 1: you know that you get some help, but UM I 362 00:19:21,640 --> 00:19:23,480 Speaker 1: recommend to if you're if you're doing this as a 363 00:19:23,520 --> 00:19:25,720 Speaker 1: hobby and you're especially if you're really concerned about the 364 00:19:25,720 --> 00:19:28,800 Speaker 1: possibility that you're going to do damage to the data 365 00:19:28,840 --> 00:19:31,720 Speaker 1: on your hard drive by doing this. I recommend doing 366 00:19:31,720 --> 00:19:34,080 Speaker 1: a little research on the internet first before you do 367 00:19:34,119 --> 00:19:37,320 Speaker 1: this with some reputable sources because UM, it really differs 368 00:19:37,359 --> 00:19:41,119 Speaker 1: operating an operating system and version of operating system to 369 00:19:41,200 --> 00:19:44,040 Speaker 1: version of operating system. UM, there are some details that 370 00:19:44,080 --> 00:19:45,720 Speaker 1: you might want to pick up on, and we don't. 371 00:19:46,880 --> 00:19:48,960 Speaker 1: You know, there's a lot. I wanted to make sure 372 00:19:48,960 --> 00:19:51,520 Speaker 1: that everybody knows that this is you know, it's not 373 00:19:51,800 --> 00:19:54,119 Speaker 1: it's not really hard to do, but you want to 374 00:19:54,119 --> 00:19:57,120 Speaker 1: be careful when you're doing it right. Each each pairing 375 00:19:57,160 --> 00:19:59,879 Speaker 1: has its own set of circumstances. So that's why we 376 00:20:00,000 --> 00:20:03,200 Speaker 1: don't really go into detail because to do to say, 377 00:20:03,280 --> 00:20:06,119 Speaker 1: like you want to run Windows and Windows Vista on 378 00:20:06,160 --> 00:20:08,879 Speaker 1: the same machine is going to be totally different. And 379 00:20:08,920 --> 00:20:11,159 Speaker 1: if you want to run run Windows XP and Lennox 380 00:20:11,240 --> 00:20:13,719 Speaker 1: on the same machine, it's just it's it's come you know, 381 00:20:13,800 --> 00:20:15,800 Speaker 1: there are different set of parameters that you have to 382 00:20:15,800 --> 00:20:18,560 Speaker 1: take into accounts. So but they're fortunately, like Chris said, 383 00:20:18,760 --> 00:20:21,520 Speaker 1: there are a lot of resources out there that pretty 384 00:20:21,600 --> 00:20:24,320 Speaker 1: much cover every single variation you can think of. And 385 00:20:24,440 --> 00:20:26,200 Speaker 1: UM and and if it's not covered. You can probably 386 00:20:26,240 --> 00:20:28,119 Speaker 1: find a forum somewhere where you ask a question and 387 00:20:28,160 --> 00:20:30,639 Speaker 1: people will be quick to answer you. So it might 388 00:20:30,680 --> 00:20:32,240 Speaker 1: even get you involved a little bit more in the 389 00:20:32,280 --> 00:20:35,000 Speaker 1: community and you'll, uh, you know, maybe you can become 390 00:20:35,480 --> 00:20:39,280 Speaker 1: more of a contributor and hobbyists. Um. And I was 391 00:20:39,320 --> 00:20:41,480 Speaker 1: going to add to talking about the complexity of it. 392 00:20:41,800 --> 00:20:43,239 Speaker 1: One of the reasons I didn't really want to get 393 00:20:43,280 --> 00:20:47,399 Speaker 1: into the multidisc a physical hard disc setup is because 394 00:20:47,400 --> 00:20:51,000 Speaker 1: it involves wiring. You have to, uh, you know, tell 395 00:20:51,080 --> 00:20:53,360 Speaker 1: each hard drive whether you know you have to pick 396 00:20:53,400 --> 00:20:56,239 Speaker 1: a master hard drive and then indicate which ones are 397 00:20:56,320 --> 00:21:01,040 Speaker 1: slave hard drives. Um. And it's you know, you're better 398 00:21:01,080 --> 00:21:04,720 Speaker 1: off going through the instructions and actually consulting uh some 399 00:21:04,800 --> 00:21:08,120 Speaker 1: experts before you get started with that, because it's it's 400 00:21:08,160 --> 00:21:10,639 Speaker 1: it's more detail than what a podcast can go into, 401 00:21:10,680 --> 00:21:14,679 Speaker 1: really yea. Um, but I was also gonna meant we 402 00:21:14,680 --> 00:21:16,960 Speaker 1: were going to talk about why people might want to 403 00:21:17,040 --> 00:21:20,159 Speaker 1: partition their hard drives and make a multi boot system. Well, 404 00:21:20,200 --> 00:21:22,200 Speaker 1: first of all, before we even get into multi boot, 405 00:21:22,440 --> 00:21:24,240 Speaker 1: you may want to partition your hard drive. I mean, 406 00:21:24,280 --> 00:21:26,040 Speaker 1: one reason you might think about doing it is just 407 00:21:26,119 --> 00:21:29,199 Speaker 1: for an organizational standpoint. So you may only have one 408 00:21:29,240 --> 00:21:31,239 Speaker 1: operating system, but you might want to partition your hard 409 00:21:31,320 --> 00:21:35,439 Speaker 1: drive into multiple UH drives so that you can store 410 00:21:35,520 --> 00:21:39,960 Speaker 1: certain information in one drive and other information and another drive. UM. 411 00:21:40,000 --> 00:21:42,920 Speaker 1: This can depending on how you organize, it can actually 412 00:21:43,000 --> 00:21:46,359 Speaker 1: speed up things like retrieving information. If you're using a 413 00:21:47,000 --> 00:21:50,280 Speaker 1: like a video processing program, and you you've put all 414 00:21:50,320 --> 00:21:53,520 Speaker 1: of your video stuff into one drive, then eventually the 415 00:21:53,560 --> 00:21:56,600 Speaker 1: operating system it knows it's just gonna go to this 416 00:21:56,680 --> 00:22:00,440 Speaker 1: one drive, which is much smaller than the overall hard 417 00:22:00,480 --> 00:22:03,000 Speaker 1: drive space, doesn't take it as long to search up 418 00:22:03,080 --> 00:22:05,560 Speaker 1: particular information and pull it back for you, so it 419 00:22:05,720 --> 00:22:10,880 Speaker 1: can in certain cases be faster to partition your hard 420 00:22:10,920 --> 00:22:14,639 Speaker 1: drive and retrieve information that way. UM. Or you know, 421 00:22:14,720 --> 00:22:17,119 Speaker 1: just from an organizational standpoint, if like you wanted to 422 00:22:17,160 --> 00:22:19,920 Speaker 1: have a drive just for all your games and then 423 00:22:19,960 --> 00:22:21,680 Speaker 1: everything like all your other data was going to be 424 00:22:21,720 --> 00:22:24,520 Speaker 1: on another drive. UM this also helps if you ever 425 00:22:24,560 --> 00:22:28,160 Speaker 1: have a if there's ever like a corrupt disc or something. 426 00:22:28,160 --> 00:22:30,639 Speaker 1: If something happens that that corrupts one of your drives, 427 00:22:30,800 --> 00:22:33,760 Speaker 1: your other drives might be safe. And if you keep 428 00:22:33,920 --> 00:22:37,440 Speaker 1: backing up your drives, which you should be doing, then 429 00:22:37,480 --> 00:22:40,679 Speaker 1: you can do a restore that hopefully won't affect your 430 00:22:40,800 --> 00:22:43,920 Speaker 1: entire computer. It just affect one drive, which still is 431 00:22:43,920 --> 00:22:46,000 Speaker 1: pretty traumatic, but it's not as bad as the entire 432 00:22:46,000 --> 00:22:49,840 Speaker 1: computer having to be restored. Yes. Now, for as for 433 00:22:50,040 --> 00:22:54,399 Speaker 1: multi operating systems, why would you want to do this? Well, 434 00:22:54,560 --> 00:23:00,320 Speaker 1: you know, we have one example, yes, um, and uh 435 00:23:00,680 --> 00:23:02,960 Speaker 1: you know there are other reasons too. For example, in 436 00:23:03,000 --> 00:23:05,159 Speaker 1: our office we have the test machine, which you have 437 00:23:05,200 --> 00:23:08,359 Speaker 1: heard about very frequently. We were trying both Windows seven, 438 00:23:08,960 --> 00:23:12,000 Speaker 1: the beta version of that before it went before it 439 00:23:12,000 --> 00:23:15,359 Speaker 1: became stopped working. It still works for two hours at 440 00:23:15,359 --> 00:23:18,080 Speaker 1: a time and shuts down without telling you. Uh you know, 441 00:23:18,119 --> 00:23:23,040 Speaker 1: since we haven't yeh Um, we'll get around to that eventually, 442 00:23:23,320 --> 00:23:26,480 Speaker 1: and uh one to UM. And it gives us an 443 00:23:26,520 --> 00:23:29,160 Speaker 1: opportunity to try both operating systems out on the same 444 00:23:29,160 --> 00:23:32,720 Speaker 1: machine without having to uh you know, we don't stall 445 00:23:32,800 --> 00:23:35,000 Speaker 1: an additional drive. And it give us a chance to 446 00:23:35,040 --> 00:23:38,720 Speaker 1: actually try out partitioning a hard drive. UM. But yeah, 447 00:23:38,720 --> 00:23:40,240 Speaker 1: I mean, if you're a hobbyist, you can you can 448 00:23:40,240 --> 00:23:43,680 Speaker 1: certainly do that and uh you know, well, the way 449 00:23:43,680 --> 00:23:46,240 Speaker 1: I figured also is that if you are let's say 450 00:23:46,240 --> 00:23:50,000 Speaker 1: you're developing UM software, it might be it might be 451 00:23:50,040 --> 00:23:51,679 Speaker 1: good to be able to do this so that you 452 00:23:51,720 --> 00:23:54,840 Speaker 1: can make sure you develop software that works on different 453 00:23:54,880 --> 00:23:58,040 Speaker 1: operating systems or different versions of the same operating system, 454 00:23:58,080 --> 00:23:59,879 Speaker 1: because you may want to even do this with the 455 00:24:00,119 --> 00:24:02,080 Speaker 1: IS like the mac os. You may want the different 456 00:24:02,160 --> 00:24:04,800 Speaker 1: versions of the macOS on one machine so that you 457 00:24:04,840 --> 00:24:07,200 Speaker 1: can make sure that things that run in in Leopard 458 00:24:07,280 --> 00:24:11,240 Speaker 1: run in snow Leopard UM without having to purchase a 459 00:24:11,440 --> 00:24:16,520 Speaker 1: machine per operating system, which gets pretty expensive. UM. And 460 00:24:16,560 --> 00:24:19,520 Speaker 1: things like legacy programs. We've talked about legacy programs before. 461 00:24:19,600 --> 00:24:22,840 Speaker 1: These are the old programs that that people and corporations 462 00:24:22,880 --> 00:24:26,320 Speaker 1: depend upon that are no longer supported by newer versions 463 00:24:26,320 --> 00:24:29,800 Speaker 1: of the OS. They just you know, either the developers 464 00:24:29,800 --> 00:24:32,320 Speaker 1: who originally created the software moved on to bigger and 465 00:24:32,320 --> 00:24:35,439 Speaker 1: better things, or it's just abandoned ware or whatever, but 466 00:24:35,560 --> 00:24:38,720 Speaker 1: there's no way of running that software in the modern 467 00:24:38,840 --> 00:24:42,879 Speaker 1: operating systems. You may want to have a machine running 468 00:24:42,880 --> 00:24:46,840 Speaker 1: the old system UM so that you can run legacy programs, 469 00:24:47,040 --> 00:24:48,919 Speaker 1: but a lot of companies don't want to, you know, 470 00:24:49,119 --> 00:24:52,840 Speaker 1: waste a machine just to do that. I mean, if 471 00:24:52,840 --> 00:24:54,560 Speaker 1: that's all it does, then that's kind of a waste. 472 00:24:54,600 --> 00:24:56,480 Speaker 1: Of space and energy and all that kind of stuff. 473 00:24:56,480 --> 00:24:58,840 Speaker 1: But if you are able to to dual boot it 474 00:24:59,200 --> 00:25:01,560 Speaker 1: so that you can run it in, you know, the 475 00:25:01,560 --> 00:25:03,720 Speaker 1: operating system that the rest of the office is running 476 00:25:03,720 --> 00:25:06,480 Speaker 1: in for most of the time, and then switch over 477 00:25:06,480 --> 00:25:09,520 Speaker 1: whenever you need to use the legacy program, then that 478 00:25:09,600 --> 00:25:12,840 Speaker 1: might make sense. Now, one disadvantage to using a multi 479 00:25:12,840 --> 00:25:15,040 Speaker 1: boot operating system is that if you want to use 480 00:25:15,040 --> 00:25:18,600 Speaker 1: the other operating system, you have to restart and boot 481 00:25:18,680 --> 00:25:22,840 Speaker 1: into the other operating system. So you're in operating system 482 00:25:22,880 --> 00:25:26,119 Speaker 1: A operating system B operating system, see, you know, and 483 00:25:26,160 --> 00:25:28,919 Speaker 1: not sharing the others, which is the advantage of a 484 00:25:28,960 --> 00:25:33,720 Speaker 1: program like Parallels or vm ware or Sun's Virtual Box. 485 00:25:33,960 --> 00:25:36,360 Speaker 1: These are creating virtual machines where you can switch back 486 00:25:36,400 --> 00:25:39,919 Speaker 1: and forth. Basically, it's it's like you see a window. 487 00:25:40,080 --> 00:25:42,200 Speaker 1: For for those of you haven't tried it, um, it's 488 00:25:42,240 --> 00:25:44,919 Speaker 1: like you have a window open in your current native 489 00:25:44,960 --> 00:25:48,560 Speaker 1: operating system, and inside that window is the other operating 490 00:25:48,560 --> 00:25:52,640 Speaker 1: system that can run programs installed on it. And uh, 491 00:25:52,840 --> 00:25:55,440 Speaker 1: it's you're not creating a partition, and well, it's sort 492 00:25:55,440 --> 00:25:57,840 Speaker 1: of creating a virtual partition really when you think about it, right, 493 00:25:58,200 --> 00:26:02,040 Speaker 1: but not a physical part not a physical partition. UM. 494 00:26:02,200 --> 00:26:05,560 Speaker 1: And uh it's kind of cool because you can say, 495 00:26:06,000 --> 00:26:07,879 Speaker 1: you know, I actually have virtual Box installed on my 496 00:26:07,880 --> 00:26:11,119 Speaker 1: Mac at home and a run uh Windows seven for 497 00:26:11,240 --> 00:26:14,720 Speaker 1: two hours at a time on it, and uh, you know, 498 00:26:14,760 --> 00:26:16,440 Speaker 1: I can I can switch back and forth from the 499 00:26:16,480 --> 00:26:19,800 Speaker 1: Mac to the PC, you know, in the same window. 500 00:26:19,840 --> 00:26:24,119 Speaker 1: Now the problem is, UM, in this case, you're dividing 501 00:26:24,200 --> 00:26:28,080 Speaker 1: up the resources very literally, because when you install a 502 00:26:28,119 --> 00:26:31,159 Speaker 1: new operating system in this virtual machine and create a 503 00:26:31,240 --> 00:26:33,560 Speaker 1: virtual machine to run that operating system, it asks you 504 00:26:33,600 --> 00:26:36,040 Speaker 1: how much memory? And we're talking RAM here, not hard 505 00:26:36,119 --> 00:26:40,040 Speaker 1: drive space. So I have let's say two gigabytes of 506 00:26:40,280 --> 00:26:43,480 Speaker 1: memory on my machine. I have to decide, well, one 507 00:26:43,480 --> 00:26:46,000 Speaker 1: operating system is gonna run let's say one gigabyte, Well, 508 00:26:46,000 --> 00:26:47,840 Speaker 1: the other one's gonna run the other. And so it 509 00:26:48,400 --> 00:26:50,960 Speaker 1: overall your performance is going to be a little bit slower. 510 00:26:51,480 --> 00:26:54,560 Speaker 1: And you know, it's not exactly like an emulator, but 511 00:26:54,760 --> 00:26:57,399 Speaker 1: it works sort of like that. And you know, because 512 00:26:57,400 --> 00:27:00,720 Speaker 1: you are running the other operating system concurrently, it's dividing 513 00:27:00,760 --> 00:27:04,000 Speaker 1: up the system resources between the two. So everything is 514 00:27:04,080 --> 00:27:07,520 Speaker 1: kind of delayed. Yeah, So if you have a really 515 00:27:07,640 --> 00:27:10,680 Speaker 1: lightning best machine, then that's not gonna matter as much 516 00:27:10,720 --> 00:27:12,880 Speaker 1: to you. But if you are, yeah, it's still gonna 517 00:27:12,920 --> 00:27:15,640 Speaker 1: be noticeable. But if you have a slow machine, then 518 00:27:15,640 --> 00:27:19,000 Speaker 1: it could become painful. So there there are advantages to 519 00:27:19,040 --> 00:27:21,440 Speaker 1: that if you have something very simple that only runs 520 00:27:21,440 --> 00:27:23,040 Speaker 1: in the other operating system. You why I want to 521 00:27:23,080 --> 00:27:25,040 Speaker 1: go that route, But um, if you really want, if 522 00:27:25,040 --> 00:27:27,159 Speaker 1: you're gonna do something like play games, you know, the 523 00:27:27,240 --> 00:27:30,680 Speaker 1: high end windows, high frame rate games, you know, first 524 00:27:30,680 --> 00:27:32,600 Speaker 1: person shooters especially that kind of stuff with a lot 525 00:27:32,600 --> 00:27:34,320 Speaker 1: of action, you're not gonna want to try to do 526 00:27:34,400 --> 00:27:36,439 Speaker 1: that through a virtual machine. You're gonna want to do 527 00:27:36,680 --> 00:27:40,080 Speaker 1: you know, dual boot and flip over together exactly, exactly. Well, 528 00:27:40,080 --> 00:27:43,959 Speaker 1: that was a good discussion about a multibooting. Yeah. Um, 529 00:27:44,080 --> 00:27:45,919 Speaker 1: we're running a little short on time. I'm not going 530 00:27:46,000 --> 00:27:49,800 Speaker 1: to go on into listener mail, but we will. We 531 00:27:49,920 --> 00:27:52,359 Speaker 1: definitely read every single one of those messages, so we 532 00:27:52,400 --> 00:27:55,920 Speaker 1: don't have an intern reading those, it's us. It comes 533 00:27:55,960 --> 00:27:59,560 Speaker 1: straight to us. Um. Sometimes it actually takes a detour 534 00:27:59,680 --> 00:28:02,600 Speaker 1: to our junk folder for some reason, even though they're 535 00:28:02,640 --> 00:28:05,240 Speaker 1: all coming to the same address. But we do make 536 00:28:05,280 --> 00:28:08,400 Speaker 1: sure we check those as well, so keep those messages 537 00:28:08,440 --> 00:28:11,520 Speaker 1: coming in our addresses is tech stuff at how stuff 538 00:28:11,520 --> 00:28:15,520 Speaker 1: works dot com. You can read all about various operating 539 00:28:15,520 --> 00:28:18,119 Speaker 1: systems at how stuff works dot com and check out 540 00:28:18,160 --> 00:28:20,560 Speaker 1: our blogs are blogs at are at blogs dot hou 541 00:28:20,600 --> 00:28:23,240 Speaker 1: stuf works dot com. We've got lots of interesting things 542 00:28:23,280 --> 00:28:26,199 Speaker 1: to say about all sorts of stuff there, and hopefully 543 00:28:26,200 --> 00:28:28,240 Speaker 1: you guys found this to be a pretty interesting topic. 544 00:28:28,320 --> 00:28:30,600 Speaker 1: It's uh, it's kind of cool to think about being 545 00:28:30,600 --> 00:28:34,440 Speaker 1: able to run various operating systems on a single machine. Yeah, 546 00:28:34,440 --> 00:28:36,240 Speaker 1: it's it's It's been kind of fun doing that on 547 00:28:36,280 --> 00:28:38,360 Speaker 1: the test machine just to get a look at the 548 00:28:38,360 --> 00:28:40,440 Speaker 1: other ones. So I like it because it lets me 549 00:28:40,520 --> 00:28:45,120 Speaker 1: break twice as much stuff on one single device. Indeed. Well, guys, 550 00:28:45,240 --> 00:28:47,400 Speaker 1: hope you enjoyed it, and we will talk to you 551 00:28:47,440 --> 00:28:52,680 Speaker 1: again really soon for more on this and thousands of 552 00:28:52,720 --> 00:28:55,520 Speaker 1: other topics.
