It is tricky, but you can dual boot Windows XP on top of pre-installed Vista. Look at this article explaining the BCD system. http://technet2.microsoft.com/Window....mspx?mfr=true

I have copied the relevant section below:

How to modify BCD when installing a previous version of Windows onto a computer running Windows Vista
To install an older Windows operating system on a computer running Windows Vista, use the following procedure.

To install a previous version of Windows onto a computer running Windows Vista

1. Install the previous version of Windows.

2. Log on to the older operating system and restore the latest boot manager by running the following. Fixntfs.exe will be in the \\boot directory of the active partition.

fixntfs /lh

3. Create a BCD entry for the older operating system by specifying the following. Bcdedit.exe is located in the \\Windows\\System32 directory of the Windows Vista partition. Description is the description of the new entry for the older operating system.

Bcdedit /create {legacy} /d “Description”

Bcdedit /set {legacy} device boot

Bcdedit /set {legacy} path \ tldr

Bcdedit /displayorder {legacy} /addlast

4. Restart the computer in order for the changes to take effect.

should just be able to install it on a different partition. I did it that way when I installed Vista and everything works fine and there's no need to edit anything or anything like that. It'll automatically start with the boot screen and you just select which OS you want to boot into. There's no way I'd install mutliple OS's on the same partition though, that's just asking for trouble..
