I have a dual boot OS setup. 250GB hardrive (1) "C" with XP Home and 400GB hardrive (2) "G" with Vista Ultimate. I want to keep "G" Vista and remove XP "C" from the other hardrive. I find alot of info on deleting vista but not xp. I've tried multiple operations to delete the partition and format the "C" hardrive, but I can't seem to figure out what I am doing wrong. Can somebody help me?
