Triple Booting XP/Backtrack5/Ubuntu11.10 steps
 

I'd like to have XP/Backtrack5/Ubuntu11.10 on my HDD. Can anyone tell me the exact steps I have to take to do that? I spent hours finding solutions and google it everywhere says different things. I got confused. All I know that I have something to edit in grub. Please give me step by step instructions. I'm new to this
additional info: XP and Ubuntu 11.10 is already installed and running.

Install xp first or install everything after xp is installed because it can't recognize linux operating systems
hope this link will help

XP and Ubuntu 11.10 I'm already using installed running. I want to attach Backtrack 5 to these two OS and boot Ubuntu 11.10 as default.

You need to ensure that you do not install Backtrack to a partition already in use by windows or Ubuntu. You haven't posted any partition information so we can't give you any more detail. If you have free space or an unused partition, you can use that. Or you can post your current partition information and someone should be able to advise you.

The first option, since you want Ubuntu as your primary system, is to install the Backtrack bootloader to its root partition. You should have an option during the installation to do this by selecting an Advanced or Expert option during the installation. If you install the Backtrack bootloader to its root/system partition, you should then be able to boot Ubuntu and run sudo update-grub from a Terminal and get an entry for Backtrack in its menu.

You can install the Backtrack bootloader to the master boot record, after it is installed and running you should have options to select windows and Ubuntu on its boot menu if it uses Grub2. I've never used Backtrack so I don't know which bootloader it uses. This would be something you would need to determine first. It it uses Grub Legacy, you will need to manually create an entry in the /boot/grub/menu.lst file after install.

  . When I'm in Backtrack terminal How do I get an entry in its menu?

There is no reason for installing Backtrack. You have no use for it. So just install windows then install ubuntu.

How do you know I have no use for it? It's not a distro I want to try but it's a tool for my self-teaching course I'm taking .

What I was saying is that after running sudo update-grub in Ubuntu, you should then have an entry for Backtrack in the UBUNTU boot menu. You won't need to put an entry in the Backtrack Grub menu.

Ok I simply followed instalation steps and changed GRUB for booting. It's working now, Thanky everyone
