I have a Compaq Persario V6000 CTO laptop (Intel Core Duo T2350; 1860 MHz; 2 GB RAM). It came pre-installed with Vista, but I had removed that and installed XP SP2. Now, about a year later, I need to re-install the OS, only this time, when I load my Windows XP CD's and I'm in the "Windows XP Professional Setup," screen, it gives me an error that it is NOT able to detect the hard drive, so the Setup cannot continue. This makes no sense, as the BIOS sees the hard drive, and Windows sees the hard drive. I restored it from the recovery disk, which was Vista, and I do NOT want to keep Vista on the system. Plus, this thing stays in Vista for about 1 minute and then self-rebots. I don't remember it being this much of PITA a year ago, but I'm stuck and want to put XP on this thing like I did before. Any thoughts? Thanks in advance.
