I was running Windows XP Pro when I signed up for the trial edition of Windows XP 64-bit Pro at microsoft.com. I downloaded the ISO and booted up the PC with that. I proceeded to install my RAID/SATA disk drivers on installation before formatting. After I installed those drivers I started the reformatting on a fresh partition. It got done formatting only to show me an error message saying that it couldn't complete formatting because of an error on the hard disk. I thought "GREAT!". So my only option was to restart and now when my PC restarts it goes through all the BIOS readings and stuff and then gets to a black screen and sits there. It doesn't say it's loading from a CD or anything at all so the only thing I can do is turn it off. Please help with this. I would rather not have to take it in to a shop. I am heading to bed now, I will check responses tomorrow. Please help. Specs in profile.
