Hey all...I am having an issue with either my computer, hard drive, or XP CD. I currently have Vista installed on my computer and am looking ot put XP on it. This computer has never had XP on it and came from the factory with Vista (2 year old HP). When I put my XP CD in, it goes through the blue screen and looks like it is going to work to reformat and then load XP on it, however it is not working and gives me an error message. I am at work right now and don't remember exactly what it says. I will update at home tonight. Any ideas on why this is not working? I don't feel like calling Microsoft and paying to speak to some guy in India (no offense) although I am sure they could figure it out. FYI...this is an older XP disc that I have had for about 4-5 years and the serial number has not been in use since I had it installed last (which will be interesting to see if it [serial number] works considering the last hard drive it was on basically fried!) I will probably have to call MS anyways b/c of that. Thanks OT for any help!
