I've installed XP Pro (64-bit but it should work the same) onto a 40GB
IDE Hard Disk and it's working well.

I have a spare USB IDE Hard Disk bay, If I put the hard disk into that
would I be able to boot XP from it ?

My PC supports booting from USB Devices, I just don't want to corrupt
the XP installation !!

Any ideas / advice

Thanks
