Vista can shrink the 'C' partition if you don't have a second partition for
XP.
You may want to use a boot manager, so you can hide Vista from XP.
Another option would be to clone Vista to an external drive.
Xp will remove Vista restore points each time XP boots.
This is for installing XP after Vista.
