I am a bit of a novice and seem to be in some trouble here.
I have recently bought a 320 gb Western digital SATA Hdd and I am getting Disk Boot Failure insert system disk and press enter. this is not working when I try. It is now saying the same thing when I put the original 160 Gb Western Digital Sata drive back in . It has a gigabyte AGP 8X motherboard. Can anyone help, I messed with bios a bit but restored the defaults and still can't boot either drive?
