Ok, so i tried to do a repair install on my xp partition and it seems the disc was corrupt...couldnt copy the necessary files from the disc, so i turned my pc off at the button and now its stuck in a loop, boots into xp setup, fails at file copying, repeat endlessly... so now i cant boot into xp at all or my Vista partition, HELP!! Im typing this from a Ubuntu live cd, from which i cant access either partition. I have my Vista install disc which i know works, is my only option a complete format then reinstall vista??
