00:00:00,065 --> 00:00:03,464
Hello, my name is Alan Pope. Welcome to this screencast.

2
00:00:03,564 --> 00:00:07,256
In this screencast we are going to look at dual boot installing Ubuntu.

3
00:00:07,256 --> 00:00:10,590
That means running Windows and Ubuntu side by side on the same computer.

4
00:00:10,590 --> 00:00:16,084
We have a computer here that has got Windows already installed and we want to install Ubuntu,

5
00:00:16,154 --> 00:00:20,330
but be given the choice a boot time, whether to run Windows or Ubuntu.

6
00:00:20,430 --> 00:00:23,776
So we are logging on now to the Windows desktop

7
00:00:23,776 --> 00:00:26,923
and I have inserted an Ubuntu CD.

8
00:00:26,958 --> 00:00:33,916
The CD I have used is version 6.06 of Ubuntu, otherwise known as Dapper Drake

9
00:00:34,016 --> 00:00:38,742
and we can see that if we go to My Computer, there is my Ubuntu CD.

10
00:00:38,742 --> 00:00:42,728
While we are here, if I right-click and select autoplay

11
00:00:42,828 --> 00:00:45,455
or if I insert the CD whilst Windows is running,

12
00:00:45,555 --> 00:00:51,539
this application starts up, showing some Windows based open source applications

13
00:00:51,639 --> 00:00:55,071
that you can install directly from the CD.

14
00:00:55,141 --> 00:00:59,791
This is useful for people who maybe aren't ready to do the switch to Ubuntu yet,

15
00:00:59,861 --> 00:01:03,742
but want to have a look at what open source has to offer.

16
00:01:05,421 --> 00:01:08,532
There are a number of applications, including a web browser,

17
00:01:08,498 --> 00:01:12,623
email client, word processor, instant messenger and graphical editor.

18
00:01:12,723 --> 00:01:15,840
These are all part of the OpenCD project.

19
00:01:15,940 --> 00:01:20,736
What we are going to do next is boot from this CD to try out Ubuntu.

20
00:01:22,938 --> 00:01:25,980
So let us reboot the PC.

21
00:01:26,085 --> 00:01:30,351
You may need to set your PC to boot from CD,

22
00:01:30,451 --> 00:01:35,561
which might need to be done in the BIOS, or you might have a menu option when you turn your computer on.

23
00:01:35,561 --> 00:01:38,918
It might mean that you have to press a certain key,

24
00:01:39,018 --> 00:01:43,638
del or a certain function key, in order to make it boot from a CD.

25
00:01:43,738 --> 00:01:48,778
And this is now booting from the Ubuntu CD that you just saw under Windows.

26
00:01:49,582 --> 00:01:53,499
You can see that there is a progress bar crossing the screen slowly

27
00:01:53,599 --> 00:01:59,128
and various pieces of text going up the screen, telling you what it is doing.

28
00:02:03,499 --> 00:02:09,023
And this is going to boot into a live environment, that you could use on a desktop or laptop PC,

29
00:02:11,121 --> 00:02:15,212
but you will also have the option of being able to install it on to your hard drive.

30
00:02:15,352 --> 00:02:18,254
Now bear in mind that we have already got windows on this hard drive,

31
00:02:18,354 --> 00:02:24,129
so we are going to have to partition the disk, so that we can fit Ubuntu on there as well as Windows.

32
00:02:24,198 --> 00:02:27,835
Now this procedure doesn't always work 100% reliably,

33
00:02:27,909 --> 00:02:32,683
so it is worth saying that you should backup everything on your Windows partition as a matter of course,

34
00:02:32,702 --> 00:02:36,348
before you attempt to repartition the disk and install Ubuntu.

35
00:02:36,448 --> 00:02:39,280
That is just a sensible precaution anyway.

36
00:02:41,103 --> 00:02:44,824
In addtion to which, sometimes this procedure doesn't actually work

37
00:02:44,924 --> 00:02:47,906
for certain makes and models of PCs,

38
00:02:48,006 --> 00:02:51,026
certain chipsets of Motherboard

39
00:02:51,026 --> 00:02:55,687
and there is an alternative CD, called the alternate CD, that doesn't boot into a live environment,

40
00:02:55,787 --> 00:02:59,991
but still allows you to install Ubuntu and that's another option you can try

41
00:03:00,028 --> 00:03:03,994
and we will probably look at that in another screencast.

42
00:03:08,467 --> 00:03:13,147
Bear in mind it is slightly slow to boot up because it it running everything from a CD,

43
00:03:13,247 --> 00:03:17,770
which is orders of magnitude slower than running from a hard disk.

44
00:03:20,552 --> 00:03:23,671
So now we have the Ubuntu desktop,

45
00:03:26,096 --> 00:03:28,877
running from the live CD

46
00:03:31,095 --> 00:03:34,497
and we could use the various applications installed

47
00:03:34,534 --> 00:03:38,368
or we could go and have a look at the disks as they are configured.

48
00:03:38,406 --> 00:03:44,082
We use the GNOME Partition Editor or gparted.

49
00:03:44,796 --> 00:03:48,893
This is gparted, the GNOME Partition Editor and you can see we have one disk in this machine,

50
00:03:48,931 --> 00:03:51,581
which is addressed as /dev/hda.

51
00:03:51,505 --> 00:03:54,813
There is one partition on there which is an NTFS partition,

52
00:03:54,851 --> 00:03:56,913
that is my Windows partition.

53
00:03:58,121 --> 00:04:01,805
It has got plenty of unused space, so what we want to do is shrink that partition down,

54
00:04:01,993 --> 00:04:05,601
and you can see, if I click on it, there is a move/resize option.

55
00:04:05,701 --> 00:04:09,379
So, directly in gparted, I could resize that partition down to make room at the end

56
00:04:09,397 --> 00:04:11,258
for my Ubuntu installation.

57
00:04:11,358 --> 00:04:13,513
Now I'm not actually going to do that in gparted,

58
00:04:13,613 --> 00:04:18,456
because the installation software has the ability to do that as well,

59
00:04:18,556 --> 00:04:22,271
so we are going to try that, but as I said 

60
00:04:22,371 --> 00:04:25,711
sometimes the partition editor can't work in certain situations

61
00:04:25,811 --> 00:04:30,184
and that is why you need to to know that gparted is there, that allow you to repartition disks.

62
00:04:30,221 --> 00:04:32,402
So I've double-clicked the install program on the desktop

63
00:04:32,458 --> 00:04:35,315
and it is now asking me which language I want to run the installer in

64
00:04:35,415 --> 00:04:37,965
and I'm going to run it in English.

65
00:04:39,393 --> 00:04:42,099
I click forward and it now asks me where I am in the world.

66
00:04:42,199 --> 00:04:47,681
This is for setting up time zone and the time on my computer.

67
00:04:48,621 --> 00:04:51,553
I have said that I am in London, which is the nearest city to where I am

68
00:04:51,653 --> 00:04:57,830
and you can see here, the current time is the same as the current time on my local machine, so that is right.

69
00:04:58,770 --> 00:05:00,950
I click forward.

70
00:05:02,134 --> 00:05:05,348
Now it is asking me what keyboard layout I have

71
00:05:07,077 --> 00:05:09,858
and down here I can test out the keyboard layout,

72
00:05:11,193 --> 00:05:15,402
pressing special keys to make sure that they all appear correctly.

73
00:05:18,071 --> 00:05:21,172
Once you have chosen the correct keyboard layout, press forward.

74
00:05:22,281 --> 00:05:26,115
Now it's asking you for your name. There is no nafarious reason why it needs your name,

75
00:05:26,215 --> 00:05:30,663
it is just so that when you display things, they come up with your name correctly.

76
00:05:31,283 --> 00:05:36,095
Here is your username, which you can choose

77
00:05:36,583 --> 00:05:40,605
and a password to secure your data and your machine.

78
00:05:40,493 --> 00:05:45,717
This first user will be an administrative account and will have quite a lot of access to control the machine,

79
00:05:45,817 --> 00:05:48,743
so we need to be careful with that password.

80
00:05:48,843 --> 00:05:53,235
And we give the computer a name.

81
00:05:55,321 --> 00:05:58,667
Now it's asking us which disk we want to install Ubuntu on,

82
00:05:58,767 --> 00:06:01,467
it goes off and scans to find out how many disk there are in the machine.

83
00:06:04,643 --> 00:06:06,335
And we get a number of options here.

84
00:06:06,316 --> 00:06:07,744
The first one is the one I am going to choose,

85
00:06:07,763 --> 00:06:11,841
resize the first IDE disk, but there are other options.

86
00:06:11,860 --> 00:06:15,356
You could wipe the disk, now I don't want to do that because I don't want to lose my Windows install,

87
00:06:15,393 --> 00:06:18,740
I want to have a dual boot installation.

88
00:06:19,622 --> 00:06:23,963
We can move this slider backwards and forwards to create the size of our new partition

89
00:06:23,982 --> 00:06:26,670
in which we will install Ubuntu.

90
00:06:26,726 --> 00:06:29,489
When I click forward it goes off to do some analysis

91
00:06:29,921 --> 00:06:32,383
and it should do the repartitioning.

92
00:06:33,661 --> 00:06:36,800
Remember again sometimes this repartitioning doesn't work,

93
00:06:36,819 --> 00:06:44,900
you might need to use gparted, alternatively you might actually need to use a third party CD

94
00:06:45,000 --> 00:06:48,433
which we will look at in just a moment.

95
00:06:55,086 --> 00:06:59,898
Incidentally the alternate CD has further options for this disk partitioning.

96
00:07:02,040 --> 00:07:05,799
Okay, so now we have a summary of what it plans to do to our machine.

97
00:07:05,574 --> 00:07:09,596
You can see down here at the bottom, it's going to add two new partitions

98
00:07:09,696 --> 00:07:13,411
in addition to our existing Windows partition.

99
00:07:13,430 --> 00:07:17,715
Partition 2 on hda first disk is going to be of type Ext3,

100
00:07:17,815 --> 00:07:20,007
that is the type of filesystem it is going to use,

101
00:07:20,026 --> 00:07:23,879
and partition 5 on hda is going to be swap.

102
00:07:29,517 --> 00:07:33,577
Swap on Linux is the equivalent of Page File on Windows.

103
00:07:36,565 --> 00:07:40,343
So now the installer is running and we can pretty much leave it alone,

104
00:07:40,456 --> 00:07:43,651
we can go off and use the applications installed here.

105
00:07:43,989 --> 00:07:47,015
So have a play around with Ubuntu while it is installing.

106
00:07:57,314 --> 00:08:03,497
You can see now that it is creating the filesystem on the second partition of the first hard disk

107
00:08:03,535 --> 00:08:06,485
and now it is actually getting on the the installation proper.

108
00:08:11,409 --> 00:08:18,889
This takes a little while, so let us go and have a look at the web while the installation is running.

109
00:08:22,742 --> 00:08:28,587
The length of the time it take to install is dependant on a few factors,

110
00:08:28,662 --> 00:08:33,549
usually the speed of your computer, how much memory you have got and the speed of your CD-ROM drive.

111
00:08:33,850 --> 00:08:38,059
Now if we open our web browser and I take you to wiki.ubuntu.com

112
00:08:40,879 --> 00:08:44,882
and in the top right we search for dual boot,

113
00:08:44,982 --> 00:08:48,998
you will find the documentation that supports this screencast.

114
00:08:49,098 --> 00:08:53,903
In fact this screencast was based on the content of some of this web page.

115
00:08:54,016 --> 00:09:00,067
It's worth pointing this out because this web page has some useful information,

116
00:09:00,161 --> 00:09:03,977
if the procedure that I have shown does not work.

117
00:09:03,995 --> 00:09:08,731
So for example there are issues with XP and NTFS

118
00:09:08,831 --> 00:09:12,847
and here it details what to do if partitioning doesn't work

119
00:09:12,947 --> 00:09:17,208
or the installer fails with some other reason to do with the partitioning of the disk.

120
00:09:18,486 --> 00:09:23,616
It also outlines down here that modern PCs do not come with a Windows CD.

121
00:09:24,556 --> 00:09:29,367
An image of the Windows CD often comes on the hard drive and you have to burn it yourself.

122
00:09:29,931 --> 00:09:35,663
So it's a check that you need make that you have a copy of the Windows CD, should you need to reinstall it.

123
00:09:36,678 --> 00:09:38,990
Now let us skip forward in time slightly.

124
00:09:44,027 --> 00:09:50,342
Of course it will actually take a little bit longer than this, but let us skip forward a bit here.

125
00:09:56,525 --> 00:09:58,630
Nearly finished.

126
00:10:03,422 --> 00:10:06,711
Okay, we are right at the end now.

127
00:10:07,482 --> 00:10:13,139
Grub is a menu that gets installed, which is the first thing you will see when you reboot the PC.

128
00:10:14,229 --> 00:10:18,815
So now the installation has finished I can continue to use the live CD if I want to

129
00:10:19,172 --> 00:10:23,156
and carry on using the applications, just straight off the live CD,

130
00:10:23,175 --> 00:10:27,648
but now that I have installed Ubuntu I probably want to reboot to the hard disk.

131
00:10:27,748 --> 00:10:32,521
So that it is quicker and I can then customise the applications for my own use.

132
00:10:33,375 --> 00:10:37,255
So if I hit the power button in the top right hand corner and reboot the PC.

133
00:10:37,459 --> 00:10:42,935
First thing you see is it shut down nicely.

134
00:10:46,796 --> 00:10:52,012
Then it will ask you to remove the CD and press enter

135
00:10:52,030 --> 00:10:55,464
and then when you turn your PC on, you need to make sure that it reboots from the hard disk

136
00:10:55,483 --> 00:10:57,413
and not from the CD.

137
00:11:01,237 --> 00:11:03,929
Of course if you remove the CD, that is not a problem.

138
00:11:03,984 --> 00:11:06,193
So here is the GRUB boot menu.

139
00:11:06,509 --> 00:11:07,957
There is a number of options here,

140
00:11:08,057 --> 00:11:10,057
There are two options at the top for Ubuntu.

141
00:11:10,157 --> 00:11:13,581
The first option is to boot normally into the graphical user interface,

142
00:11:13,599 --> 00:11:18,760
the second is recovery mode, which with some assistance you can fix some problems that can occur.

143
00:11:18,797 --> 00:11:21,061
The third one does a memory test,

144
00:11:21,470 --> 00:11:25,646
memory problems can cause a lot of issues in PCs these days,

145
00:11:25,683 --> 00:11:27,001
that is why there is a test there.

146
00:11:27,057 --> 00:11:30,175
And the last option is the other operating system installed.

147
00:11:31,011 --> 00:11:34,111
If we choose the first option on this list and boot up, you can see now

148
00:11:34,211 --> 00:11:36,211
it is booting into Ubuntu.

149
00:11:36,357 --> 00:11:39,159
And again we get the progress bar going across the screen

150
00:11:39,259 --> 00:11:41,259
and the messages going up the screen.

151
00:11:42,371 --> 00:11:46,139
We happen to use version 6.06, otherwise known as Dapper Drake,

152
00:11:46,807 --> 00:11:51,726
But you could install a newer version, Edgy Eft version 6.10 is also available

153
00:11:51,912 --> 00:11:54,436
and it looks much the same.

154
00:11:54,536 --> 00:11:56,088
So this is the log on screen

155
00:11:56,181 --> 00:11:59,633
Now if we log on to Ubuntu using the username and password

156
00:11:59,733 --> 00:12:02,325
that we created during the installation.

157
00:12:02,919 --> 00:12:05,536
We should get the Ubuntu desktop appear

158
00:12:05,636 --> 00:12:10,362
You will notice that it is significantly faster booting from the hard drive

159
00:12:10,462 --> 00:12:12,330
than it was booting from the CD-ROM.

160
00:12:12,430 --> 00:12:14,430
There we go, we are straight into the desktop.

161
00:12:15,355 --> 00:12:17,342
There is our CD-ROM

162
00:12:18,808 --> 00:12:22,391
and our applications we will find under the Applications menu

163
00:12:22,491 --> 00:12:26,289
and there are loads of other good stuff up there, which will be covered in other screencasts.

164
00:12:28,442 --> 00:12:32,043
That is it, we have got Ubuntu installed and let us just do the final check

165
00:12:32,117 --> 00:12:35,681
We will reboot the PC and make sure that we can still get into Windows.

166
00:12:39,486 --> 00:12:45,222
So if I choose Windows XP from the boot menu, GRUB.

167
00:12:45,322 --> 00:12:47,969
There we go, it boots into Windows, no problem!

168
00:12:54,911 --> 00:12:57,584
It is all looking good.

169
00:13:00,072 --> 00:13:02,559
Just a final check,

170
00:13:02,659 --> 00:13:05,752
by logging on.

171
00:13:10,299 --> 00:13:12,582
This all looks good

172
00:13:12,682 --> 00:13:13,900
Okay, so in summary

173
00:13:14,000 --> 00:13:17,093
We can install Ubuntu on a disk that already has Windows on it.

174
00:13:17,594 --> 00:13:20,750
by resizing the partition that Windows is in

175
00:13:20,850 --> 00:13:23,720
leaving about ten gigabytes free for Ubuntu to be installed.

176
00:13:23,850 --> 00:13:26,337
and the installer sets up GRUB so that we can choose which 

177
00:13:26,437 --> 00:13:28,437
operating system to boot to.

178
00:13:28,537 --> 00:13:29,641
Thanks very much for watching,

179
00:13:29,771 --> 00:13:34,226
