Disk Boot Failure..

[Boscher]

Good CD! Helped me out a few times with similar problems. Also Ultimate Boot Disk.

To the OP, whats your PSU wattage? And full specs?

Full spec is

Q6600
IP35 Pro
4GB
900W OCZ PSU
Many harddrives

The wrong hard drive is selected in the bios as the first boot drive.

Even though you only have one its trying to boot from one that isnt there thus the error.
Happened to me and drove me nuts for ages till i realised it was set to boot from hard drive 1 instead of hard drive 0.

Hope that sorts it
