Redoing XP on the Athlon

So basically after I got xubuntu all installed on the athlon, I decided to boot back to XP and do something, but unfortunately the install of XP got canned. I don't feel like going into the details because it's so depressing but basically I had to end up doing a COMPLETE reinstall, loosing datas. Most of them were mirrored on the thinkpad so it was ok.
