bootable Xp clone

This is my first post ever, so thanks in advance for any advise.
I have an XP image on an external HD, Cloned by Acronis.
I want to install it on a larger HD, now running Vista, on a notebook and make it dual bootable.
The XP image is most important, as it has tons of programs that vista doesent support, and data that i use daily. The Vista can be dumped and reinstalled if required.
So i guess I need to know my best and easiest options. Thanks again!
