Ok, I came to the conclusion that my used hard drive I bought off ebay is DAMAGED. I tried installing: Windows XP PRO, Windows XP PRO CORP, Windows 2000 PRO, Red Hat 9 LINUX, and all of them were bootlegged. So, I tried installing windows XP HOME I got from Dell and I got the same results. I don't know what it is, the seller told me the hard drive was never used. Maybe I don't know how to format and partition but it seems like I'm doing it right. I don't know how many times I have to format, I did it once and the cpu restarted and came back to the blue menu: press enter to setup XP, press R to used recovery console, press F3 to quit. I press enter AGAIN and brings me to the license agreement AGAIN, and now it asks to me to select a partition I want to setup XP in. So I choose the partition I just fomatted, then it says, There's already a WINDOWS file, choosing it may cause the operating system to disfunction. CLick yes to proceed, it will delete all files on this partition (I just did that, xp copied all files after I was formatting, so basically I'm starting over again). So It has to be the hard drive.
