I have a new build system with a AN8 32X SLI mobo and an AMD 4000+ processor. I'm trying to set it up with a Maxtor 200GB IDE hard drive. I can get Windows XP Pro to install the necessary files onto the hard drive, but I can't reboot from the hard drive to complete installation. The system keeps trying to boot from CD, even when I remove the CD from the boot sequence. When I remove the XP install CD from the drive I get an error that the boot media is invalid. It's as though the BIOS recognizes the drive (it does show up properly in the BIOS and XP seems to be able to copy to it) but won't let me boot to it. Is there some BIOS setting that I'm overlooking that will get it to boot the drive? The HD boots fine in another machine.
