I have my pc set up with two sata drives (not raid) and each set up with WinXP Pro (but different versions i.e. one with basic WinXP Pro and the other Win XP Po SP2 RC1).

No problems with the set up and can see both drives in Windows Explorer, shift files etc.

So, the question is can I choose to boot up from either disk and if so how (other than physically switching the cables around).

Thanks for your time and help.
