Hi Will,
You cannot install them on the same system volume, you need two separate
partitions at a minimum. The proper order, as always, is to install the
older OS first. Also, one caveat: XP when booted will wipe out Vista restore
points. The solution to this issue is to hide each install volume from the
other using a third party boot manager.
An alternate solution, if your preferred software needs XP, is to install
Virtual PC and run XP under it (but this would have to be the 32-bit
version). Then you can access the XP install without rebooting and shutting
down Vista.
