If you install XP with Vista as your first drive in boot priority, you will
overwrite the Vista boot with the XP boot and you won't be able to boot
Vista. You can correct this later with a Startup repair using the Vista
install DVD, you may need to run it up to 4 times before it works. Your
choice of my original recommendation or this one.
