I'm really confused. I dual boot XP and 7 (installed 7 first, using your guide) and was following your directions on deleting it. Unfortunately, for some reason, only Windows 7 is listed where there should be two OSs. Any ideas?
EDIT: lol, i just realized 2 people above just had the same issue. Never mind. XD But I still have one question: Afterwards, how do I delete everything on the hard drive? Do I just click "Format..." I just want to clear it off now.
EDIT 2: Never mind, lol, I got it all down, just disregard this post. Thanks for your help. XD
