1 00:00:00,200 --> 00:00:00,300 2 00:00:00,467 --> 00:00:03,791 Hello, My name is Alan Pope and welcome to this screencast. 3 00:00:03,910 --> 00:00:08,101 In this screencast we are going to look at downloading and burning the ISO image of Ubuntu 4 00:00:08,201 --> 00:00:12,631 We are going to do this on a Windows Computer that's not yet had Ubuntu installed. 5 00:00:12,731 --> 00:00:16,601 So first of all we are going to log on to the Windows XP desktop. 6 00:00:17,820 --> 00:00:19,873 This is a pretty standard install of Windows XP, 7 00:00:19,977 --> 00:00:25,551 that's had all of the usual security patches, for what they are worth, applied. 8 00:00:28,246 --> 00:00:31,434 Now, we start up Internet Explorer 9 00:00:32,977 --> 00:00:34,955 I have set a few homepages here, 10 00:00:35,055 --> 00:00:37,620 to make it is easier for me to get back to these pages later 11 00:00:37,720 --> 00:00:39,230 as we go through the screencast. 12 00:00:39,330 --> 00:00:41,044 Here is the Ubuntu homepage. 13 00:00:41,144 --> 00:00:43,575 Now over on the right hand side here you can see the ShipIt service, 14 00:00:43,675 --> 00:00:45,324 where we can order free CDs. 15 00:00:45,424 --> 00:00:48,921 And on the left we have the ability to download CD images. 16 00:00:49,021 --> 00:00:52,266 If I click that link it takes me to the Downloading Ubuntu page. 17 00:00:52,366 --> 00:00:55,953 And here you can see there are currently two releases that we can choose from. 18 00:00:56,053 --> 00:01:00,125 The newest release otherwise known as Edgy Eft, version 6.10 19 00:01:00,225 --> 00:01:03,829 And there's also the Ubuntu with Long Term Support (LTS), 20 00:01:03,929 --> 00:01:08,673 which is otherwise known as Dapper Drake, version 6.06 21 00:01:08,777 --> 00:01:13,489 Notice 6.10 means that it was released in 2006, October. 22 00:01:13,589 --> 00:01:17,921 and 6.06 is 2006, June. 23 00:01:19,267 --> 00:01:21,275 Down here you can see the mirrors 24 00:01:21,375 --> 00:01:24,447 from which we can download download the images of the CD. 25 00:01:24,547 --> 00:01:29,173 Now mirror is just a site that contains a copy of the Ubuntu site. 26 00:01:29,273 --> 00:01:32,147 So you can see there's lots of mirrors dotted all around the world, 27 00:01:32,247 --> 00:01:34,228 you should choose the mirror nearest to you. 28 00:01:34,328 --> 00:01:37,915 Now I've selected the mirror that's nearest to me in the UK 29 00:01:38,015 --> 00:01:42,983 and this is what we get, a listing full of files that we could download. 30 00:01:45,061 --> 00:01:47,298 Now you'll notice they're all called Ubuntu, 31 00:01:47,398 --> 00:01:48,977 If we go to the parent directory, 32 00:01:49,077 --> 00:01:54,014 you'll see there's also images for Kubuntu, which is the KDE derivative. 33 00:01:54,114 --> 00:01:56,417 and Edubuntu. 34 00:01:56,867 --> 00:01:59,935 If we go back into the 6.06 directory, 35 00:02:01,645 --> 00:02:04,661 you can also see that actually 6.06 is linked to dapper, 36 00:02:04,761 --> 00:02:08,019 so 6.06, Dapper is the codename for that release. 37 00:02:08,413 --> 00:02:13,005 So here we have the Ubuntu images, version 6.06 38 00:02:13,105 --> 00:02:18,198 Now it says -1, that means this is a release that was made after 6.06 came out. 39 00:02:18,298 --> 00:02:21,487 In fact you can see the files are date stamped in August. 40 00:02:22,314 --> 00:02:27,425 Now there are lots of different types of CD, alternate, desktop, server. 41 00:02:28,737 --> 00:02:33,757 The server CDs are usually used for... well servers that are in some kind of data center, 42 00:02:33,857 --> 00:02:35,851 usually without a GUI. 43 00:02:35,951 --> 00:02:38,954 The desktop CD is a live CD, you can boot from 44 00:02:39,054 --> 00:02:43,541 and the alternate CD is often used in situations where the desktop CD doesn't work. 45 00:02:43,641 --> 00:02:47,610 Maybe if you have a strange set of hardware on your desktop. 46 00:02:47,987 --> 00:02:50,708 Next we have the chipset that is used in your machine. 47 00:02:50,808 --> 00:02:58,117 This could be Intel based, AMD64 based, PowerPC based or SPARC. 48 00:03:00,208 --> 00:03:02,891 Finally there's a number of different files within each category, 49 00:03:02,991 --> 00:03:07,496 this is the one we're going to grab, the desktop CD for i386. 50 00:03:07,596 --> 00:03:13,213 Notice there's ISO images, Torrent files and Jigdo files. 51 00:03:14,698 --> 00:03:18,042 We're going to grab this ISO here. 52 00:03:19,562 --> 00:03:21,574 There's a few ways you can download this. 53 00:03:21,674 --> 00:03:24,465 There's also a Torrent file, which you can see is much smaller, 54 00:03:24,565 --> 00:03:29,277 it isn't actually the image, you need a third party product like BitTornado here. 55 00:03:29,724 --> 00:03:34,159 I've already downloaded and installed BitTornado on this Windows machine. 56 00:03:34,952 --> 00:03:38,016 What BitTornado is, is a Bittorrent client, 57 00:03:38,116 --> 00:03:42,555 this is a peer to peer software that can allow you to legitimately download software. 58 00:03:42,655 --> 00:03:46,723 So if I click the Torrent file it should open with BitTornado. 59 00:03:46,931 --> 00:03:49,653 Now the Windows firewall has popped up to say 60 00:03:49,753 --> 00:03:52,592 we've got a program here that's trying to access the Internet. 61 00:03:52,692 --> 00:03:54,448 Do we want to block it or unblock it 62 00:03:54,548 --> 00:03:56,792 or postpone this until later. 63 00:03:57,127 --> 00:03:59,880 This is the Windows firewall, other firewalls will do a similar thing. 64 00:04:00,226 --> 00:04:03,380 If we allow it to access the Internet, 65 00:04:03,480 --> 00:04:06,392 then we can choose where we want to save the ISO image. 66 00:04:06,492 --> 00:04:10,253 And then BitTornado starts downloading. 67 00:04:10,353 --> 00:04:14,958 Now I've already downloaded the ISO image, so actually I'm going to close this, 68 00:04:16,308 --> 00:04:19,251 And I've downloaded that ISO image. 69 00:04:19,649 --> 00:04:22,682 There's another option here and that's Jigdo, 70 00:04:22,782 --> 00:04:24,794 Now this isn't available for every image, 71 00:04:24,894 --> 00:04:27,408 this is just another alternative way to download the image. 72 00:04:27,508 --> 00:04:29,556 Generally most people don't use that. 73 00:04:29,656 --> 00:04:32,446 Most people use the ISO image or Bittorrent. 74 00:04:32,944 --> 00:04:37,050 Now here's the ISO image, you can see it's quite large 700MB. 75 00:04:37,237 --> 00:04:39,301 About the size of a CD. 76 00:04:39,401 --> 00:04:43,629 Now before we burn it onto a CD, we want to make sure that we downloaded it successfully. 77 00:04:43,729 --> 00:04:47,818 We can do that by running a checksum program on it. 78 00:04:48,108 --> 00:04:53,565 And this program here HashTab can perform a checksum on the file. 79 00:04:53,977 --> 00:04:56,439 I've already downloaded and installed this as well. 80 00:04:56,539 --> 00:04:58,807 There's the download. 81 00:04:59,689 --> 00:05:03,342 Once you've installed it, you can then right-click an ISO image, 82 00:05:03,442 --> 00:05:06,012 choose properties 83 00:05:06,250 --> 00:05:08,709 and you'll see you get an extra tab here called File Hashes. 84 00:05:08,809 --> 00:05:12,832 And as soon as you flick to that tab it starts calculating mathematically 85 00:05:12,932 --> 00:05:16,174 a checksum, it's a called an MD5 hash. 86 00:05:16,274 --> 00:05:18,961 And if we go back to where we downloaded the file from, 87 00:05:19,061 --> 00:05:23,492 you can see we've got this file full of MD5 sums or hashes, 88 00:05:23,596 --> 00:05:25,535 for each of the different ISO images. 89 00:05:25,635 --> 00:05:30,819 This is the one that we downloaded and so this is MD5 sum or hash value, 90 00:05:30,919 --> 00:05:34,818 the computed value and if we copy that. 91 00:05:36,112 --> 00:05:41,963 and go back to where our hash was being calculated and paste it in here. 92 00:05:42,933 --> 00:05:47,437 When we hit compare, it tells us the hashes match. 93 00:05:47,537 --> 00:05:52,107 So therefore the ISO image was downloaded successfully and it's not corrupt in any way. 94 00:05:53,942 --> 00:05:57,387 Now that we've downloaded it we might want to burn it onto a CD. 95 00:05:59,188 --> 00:06:04,420 There's a free CD burning bit of software called ImgBurn 96 00:06:05,627 --> 00:06:10,496 Again I've already downloaded and installed this on this Windows PC 97 00:06:13,729 --> 00:06:15,672 and there's the download. 98 00:06:16,395 --> 00:06:20,259 Once you've installed it, you can right-click an ISO image 99 00:06:21,433 --> 00:06:24,379 and choose Burn using ImgBurn. 100 00:06:26,055 --> 00:06:30,265 Now it's slightly unfortunate that this PC doesn't actually have a CD burner built-in. 101 00:06:30,365 --> 00:06:33,520 So I can't show you the burning, but that bit is not really particularly interesting. 102 00:06:33,862 --> 00:06:39,124 Here's ImgBurn opened, it's opened the ISO image, it looks at the detail about 103 00:06:39,315 --> 00:06:42,487 the ISO image there or type of file it is. 104 00:06:42,587 --> 00:06:45,655 And then down here you can see it says no CD writers detected, 105 00:06:45,755 --> 00:06:47,295 so it can't actually burn it. 106 00:06:47,395 --> 00:06:52,648 If it did find a CD burner, then down here we'd find this button would be illuminated 107 00:06:52,748 --> 00:06:58,759 and I could press that button and that would then burn the ISO image on to a CD. 108 00:06:59,327 --> 00:07:01,754 Obviously you could use any CD burning software. 109 00:07:01,854 --> 00:07:04,728 But it must burn the image on to the CD 110 00:07:06,026 --> 00:07:10,288 Now let's assume I've burnt that and inserted the CD into my CD-ROM drive. 111 00:07:10,388 --> 00:07:13,283 You can see there my Ubuntu CD is in the drive 112 00:07:13,383 --> 00:07:16,884 Now under Windows I can actually open this CD 113 00:07:16,984 --> 00:07:20,256 and there is autoplay on it, so if you insert it while Windows is running, 114 00:07:20,360 --> 00:07:25,449 it should automatically start this application you're seeing now. 115 00:07:27,440 --> 00:07:32,516 There's a number of Windows applications on the Ubuntu live Desktop CD. 116 00:07:32,616 --> 00:07:37,207 It's only on the live desktop CD, not the server or alternate CD. 117 00:07:37,480 --> 00:07:42,227 You can see here there's a number of applications that you might want to try out under Windows. 118 00:07:42,327 --> 00:07:44,772 Open source applications of course. 119 00:07:44,872 --> 00:07:48,165 There's a web browser, email client, word processor, 120 00:07:48,265 --> 00:07:52,143 instant messenger and graphical editor. 121 00:07:53,268 --> 00:07:58,531 Each of these can be installed on Windows, straight from the CD 122 00:07:59,794 --> 00:08:04,299 These are all part of the OpenCD project, which is separately available. 123 00:08:05,040 --> 00:08:09,129 Now alternatively you can boot from this CD and try Ubuntu out 124 00:08:09,229 --> 00:08:12,522 and maybe even install it if you choose to. 125 00:08:12,622 --> 00:08:15,672 And that will be the subject of another screencast. 126 00:08:18,231 --> 00:08:22,181 So in summary, you can get the ISO image from the Ubuntu Mirrors, 127 00:08:22,281 --> 00:08:27,756 download it, check it, then burn it and then either view it from Windows 128 00:08:27,856 --> 00:08:33,780 or reboot and boot to it, to get Ubuntu. 129 00:08:33,880 --> 00:08:37,532 Thanks for watching.
