Long story short: i've got an xp install and a vista rc1 install- I used to dual boot, using vista's bootloader. That became messed up, and I had to reinstall vista rc1. Now there is no boot choice screen- vista just comes up. My xp partition is still there, I can see it in vista. I'd like to get rid of vista, and get my xp back. How can I go about doing this?
