Hello, This is a little weird situation. My pc originally had two XP pro installed with one being corrupted. The corrupted one was there and I just didn't bother to delete it. So installed Vista the other day. Thought with XP installed first so I should automatically have two options, i.e. dual boot at start-up. However, I found out somehow Vista recognized the corrupted XP and at start-up I see Vista as the only OS there. I guess I can use bcdedit but really don't know what to do because of this unusual case. Can you guys please help here? Thanks!
