I can no longer boot from the hard disk or any other device. In the bios under "fixed hdd" it says none and diagnostics says no hard disk present. I know the drive has not failed as it works fine in another machine and I have tried other drives as well. Additionally I cannot boot from a usb stick, a usb cd drive no matter what options I set. When I run diagnostics it says: Error Code 2000-0221 interval timer not functional, the solution when I enter the error code on the website is to update the bios. The bios is only A02, but I cannot update it if I cannot boot anything. Help!
