Not sure if this is a hard drive issues. I bought a new 250 gig Seagate HD to put into my Asus A8N SLI deluxe. After I hooked it up. I was asked to partition it. So I did as to what it said to. I installed Windows XP Pro. And when it started the reboot I get the message. " Error loading operating system". I have been looking on how to fix this with no luck. Please help.
