(I didn't get to the point where I fully completed the XP set-up, but when I boot into Vista there's a folder on the C: drive called Windows.0 which I think is the XP, but I'm assuming there are extra bits and pieces - registry etc - that I'd need to delete as well)

Unfortunately there is currently no system restore point otherwise this would be somewhat easier... help!
