Computer will not re-boot after using Knoppix
While trying out various Live-CD distros I booted Knoppix.
After shutting down using the proper Knoppix procedure my computer will not re-boot, either in Windows xP or and of the Live CDs. It just hangs at the bios display. Pressing F1 does no good.
The computer recovery disk does not boot either.
I have tried rebooting with Live-CD in each of my CD Drives.
Computer is a 3 year old Compaq Athlon 64, and never any problem with it until I used the Knoppix Live CD.
Anyone any idea of what I should do now?
