Right now, I have a new computer I built but it has no OS. I have to wait about a week before I get authorization to obtain a copy of XP from the school. Since it's an Athlon64, I figure I'd download the preview version of Windows XP 64-bit and use that until I get my copy from the school. Anyhow, can anyone go through the steps of effectively formatting the harddrive after I'm done with the preview version so I get a clean start? I'm new to XP (yeah, I'm late) and I just wanted confirmation so I don't do anything stupid. BTW, it's SATA. TIA
