Regardless of what drive letter Vista assigns itself, which is normally C:\,
it only applies when Vista is loaded. If you boot back to XP, the drive
letters and associations there should remain unchanged from their current
BootIT NG does allow you to hide volumes from a booted OS fairly easily, and
personally I would recommend it as booting into XP without the Vista volume
hidden from it will cause the loss of all of Vista's system restore points
(this is a known issue).
