If you're 100% sure the BIOS is set to boot off the correct disk once
it's been wiped and reinstalled (you don't have a USB flash drive or MP3
player plugged in, do you?), then it's possible a "virus protection"
setting on the BIOS is blocking overwriting the MBR.
Some BIOSes have a "virus protection" "feature" (*cough*) which
basically blocks any attempts to write to the MBR. Or, in practice, I
would imagine that it silently ignores attempts.
