Rolling back to XP Home

I've attemt to install Vista Home Premium but after installation it tried to
logon to Vista for first time it reboots and will not logon - ask me to
either repair or roll back to earlier working version of win. I've tried
repair and it just runs for hours with no results. I want to roll back to XP
but not sure how to do that. I've already registered my Vista copy as part of
the installation process. Any help would be appreciated.

Thanks

Have you tried just re intsalling XP? like the boot from CD way, then format
your C: (if you are not worrid about loosing stuff) and start clean.
