Currently on my mac pro (2.66Ghz) I have two hard drives. One contains Leopard and the other hd is used for Time Machine back-ups. I want to add another hard drive that will contain Leopard and Windows XP using Bootcamp. After I install Leopard on the newer hard drive how can I choose which hard drive to boot from? Also, on a bad day I want to boot to the XP partition on the new drive - how will that be handled? Thanks.
