Q: I have done a clean installation of Windows Vista and now I would like to put Windows XP back on by dual booting. How is this accomplished?

A: No problem. Just use Vista's Drive Management tool to create and format a new partition. Shrink the original partition to make room for Windows XP. Once the new partition is all set up, boot from your Windows XP CD and perform a clean installation to your newly created partition. Once the installation is complete, you can use a program like EasyBCD to restore your Vista boot.
