yes it's possible. you have to configure grub with some info at the end for booting XP.
Code:

title Windows XP Professional
rootnoverify (hd0,0)
chainloader +1

i'd use another disk to do this, if i were you.
if you have free space on your drive, you can make partitions just fine.
if not, you'll have to resize them using partition magic or something similar.

Keep in mind that if you use a spearate disk, I think you will have to use something like

Code:
title=Windows XP
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive
chainloader +1


in grub.conf

If you want to install linux on the same disc you'll probably need to resize your NTFS partition. Here is a post where various options for resizing an NTFS partition are discussed. Of course you should listen to my suggestions in the post :wink:. Seriously though I installed Gentoo on a Windows XP machine, and my meathod for resizing an NTFS partition worked for me with no data loss whatsoever.

You would need to do the mappings if Windows was not on the primary hard drive.

Also, note that if you should reinstall Windows again later on, it will overwrite the MBR, and hence erase your grub setup. As an alternative to using grub on the MBR, you can actually configure the boot loader in Windows to be able to load Linux.

See the following as a guide:
