How do I install xp over ubuntu and keep both?

[Armed Nuke]

I have a system with grub installed. I have vista on one partition with ubuntu on another. I want to install xp but i don't want to wipe the master boot record and make ubuntu and maybe vista inaccessible. Is there any way that i can do this?
