Have you tried a different disk? Does this disk work on other computers?
You're just seeing the PXE boot message because the computer can't read the disk.
Have you tried the manual boos selection option? PC should say "hit key to select boot device".
Yes the disc works on other pc's. I have multiple install discs.
I've tried f10 and chosen boot from cd, with the same error... But when i do this with linuxlive cd, works fine.
i've ruled out a bad drive, bad discs
