Ubuntu / Vista dual boot

and keeping previous Ubuntu

You need this:
  • Ubuntu Dapper Drake Live-CD
  • Windows Vista Beta2 DVD (or a fast connection to download it)
  • Some time to spare

This tutorial guides you through the steps of installing Windows Vista on a computer which already have an Ubuntu installation.

I wrote this tutorial because I haven't found a "Ubuntu/Vista dual-boot" that works when Ubuntu is already installed. There are only tutorials saying "Install Vista first, then Ubuntu!".

But if you have a working Ubuntu and you don't want to reinstall everything?! Then read this...


Ubuntu Logo

Most of you out there have propably heard of Windows Vista: the next generation of Windows from MS that is going to replace XP as desktop standard. It is still in beta stage and is not for stable enough to use as your primary os. That is why you should have a dual-boot install.

Windows Vista Logo

Microsoft has made Vista a public beta, meaning that you can download it for free(!) and try out (but only use it for a year or so...)

As primary OS I use the brilliant Linux distribution Ubuntu Dapper Drake. Now I wanted to make my computer able to start both Ubuntu and Windows Vista...

Before leaving Ubuntu you have to prepare your harddrive. It can be done with gparted. In a Terminal:

> sudo apt-get install gparted
> sudo gparted

Or if you prefer to do it in a gui:

There are lots of guides to help you partition your harddrive. resize your partitions and leave room (unallocated) for Vista. It needs at least 15 GB space. I recommend 20+ GB. I installed Vista on a second harddrive, but a single drive with lot of space would do it.

Vista is easy to install, almost as easy as Ubuntu. During the install choose the empty space to create a new ntfs partition.

By experience I know that Microsoft don't care about the user; they will just run over you. The installer for Vista is a good example of that. It deleted my Ubuntu loader (GRUB). Next time I booted the machine it loaded Vista. I got no option to start Ubuntu. The same will happen to you, my friend. But do not fear! Ubuntu is a Linux distro, and you can always make Linux work again.

Well, hopefully Vista is working now. You can play around with it for a while if you want. I got addicted to a small game called Inkball...

Here is more info about GRUB's way of naming the disks.

Now stop playing! You must have your Ubuntu to work again. Microsoft erased GRUB and replaced it with it's own crappy loader (wich cannot load Linux). It's time to get GRUB back into the MBR. Find your Ubuntu Live-CD (other Live discs may also work) and boot it. Then launch a terminal:

> sudo grub

grub> root (<press tab>

Now you will see a list of available harddrives if you have several (In my case hd0,hd1). Choose the one where you have ubuntu (probably hd0)

grub> root (hd0,<press tab>

This time you should see a list of partitions and their filesystems on the drive. This is what it may look like:

grub> root (hd0,
 Possible partitions are:
   Partition num: 0, Filesystem type unknown, partition type 0x7
   Partition num: 2, Filesystem type is ext2fs, partition type 0x83

Note the number of your Ubuntu partition (with ext2fs filesystem). Also remember (or write down) the partition number with an unknown filesystem 0x07; that is your Vista on an ntfs partition. Now set grub's root to the right partition (In my case (hd0,2)) and then install grub to mbr.

grub> root (hd0,2)
grub> setup (hd0)
grub> quit

Now restart your computer! You should see GRUB loading and you are able to boot Ubuntu. The last you have to do now is to add Vista to the GRUB list. Once again, fire up a terminal:

> gksudo gedit /boot/grub/menu.lst

At the bottom of the file add the following:

title  Microsoft Windows Vista Beta 2
root   (hd0,0)  #Remember Vistas partition number?
savedefault
makeactive
chainloader +1

Save the file and restart your machine to see if it's working. Hopefully it is. It worked fine for me. Now enjoy your dual boot system!

Hello Zia!

I can't tell you exatly wich partition that is the right one, since you have no type 0x83 (ext3). That is the Ubuntu standard filesystem.

0x7 is a windows ntfs disk, and probalby not Ubuntu.

I would try with number 4.

Test this:
root (hd0,4)
cat /etc/fstab

If you get any output this is the disk. If you get a "File not found" it's wrong

Hey Eric,

You might want to add that you have to set the "boot" flag on the unallocated/unrecognized partition after you create it using gparted if you plan on installing vista on the same hd as ubuntu. Otherwise, vista will keep saying that it does not meet the criteria when you try to install it on that partition.

Any ideas on when I try to run the command 'setup' after I specify the root drive I receive: Error 11: Unrecognized Device String. Thanks for any help!

Usman, what do you mean? Sorry, just converted to Linux, but still kind of need vista.

I tried your method, but I didn't know where to put grub. I have Vista on (hd0,0) and Ubuntu 6.10 (edgy) on (hd1,0). What can I do to get my Ubuntu to boot?

I'm having some troubles. Some distros such as Sabayon will automatically place Vista in GRUB, and even when I place it in there manually I get the same error, "BOOTMGR is missing, press Ctrl+Alt+Del to restart" Any ideas? I've been scouring the web for a solution, no luck, even with fresh installs.

Unfortunately i followed this guide and lost the Vista bootloader.

I entered everything fine in the menu.lst but i get a GRUB Error 18: Selected cylinder exceeds maximum suported by BIOS

This did not happen back when i had XP and i was triple booting (vista, xp and ubuntu) thru it so there is no problem with my BIOS being old and can't recognise high capacity disk drives and stuff like that.

Hello,

I have a dual boot Ubuntu and Windows Vista system on one hard drive. Grub works very nice and I also setup one logical 5GB NTFS partition so that I could share files between Linux and Windows. The trouble is that I can write to the partition with Windows but not with Linux. I've tried changing permissions (from read to read and write, it is owned by unknown) however I can't seem to do that within Ubuntu Linux. Note, I don't even know how to login as root in Ubuntu. I'm a bit new to Ubuntu so maybe I'm missing something obvious. Do you have any suggestions?

Thanks!!

Do not use "Setup (hd0)" because it will corrupt or remove your Vista loader. If you corrupted the Vista loader and Vista will not boot, use Vista disk and do a repair. You might have to do it a couple of times for it to restore the loader.

Use "Setup (hd0,0)" instead.

I was having xp & ubuntu, i had removed xp (hd0,0) and installed vista. I did as above instead of >grub setup(hd0) i did >grub setup(hd0,0) as per the last post. I could not start vista as it was coming back to grub again and again. After repairing the vista boot loader, i did exactly as per the above and can boot vista & ubuntu.
Thanks a lot pal.

Good info.

When in grub, simply pressing tab didn't work for me, it just came back blank.

I used the following command from inside grub to find the correct setting:

grub > find /boot/grub/stage1

Well, I tried installing Ubuntu onto my laptop that had Vista already. Everything seemed to go well until I could not figure out how to get Ubuntu to recognize my wireless driver. So, as disappointing as it was, I had to uninstall Ubuntu...
