[jc6699]

I'm trying to rebuild a old computer to my wife's brother it's a abit AV8 motherboard with a amd athelon fx64 proccessor. The problem I'm having is Disk boot error,insert system disk and press enter! what does that mean? I tried to install a new WD Caviar SE16 320gig sata hard drive. I checked the 2 sata ports on the mobo and I know they work fine, I also checked all the sata power connectors and they also work fine, does this hard drive have a off switch I am missing? anyone know what the problem is?

It means that the BIOS can't find a bootable partition. If you're trying to boot from CD (to install Windows or something), change the boot order in the BIOS to include CDs.
