dual OS possible using backup HD?

[Alsenor]

I have an HP 7763w PC, which came with Vista.
It has that vertical bay in the tower front for a backup (or portable?)
drive, that can be popped in and out easily.
I really would like to have XP on my machine again, but am a little
concerned about changing the main HD, or making a partition on it, fearing
unforeseen problems.
Can I install it on the BU drive? Or what would be a good way to be able to
boot into either OS at my choice?

A point to remember about Virtual PC - USB ports are not avialble.

The BU drive has a USB interface, so the answer is no.

Use a removable drive bay and two separate drives.
