Packard Bell, can't get into BIOS
I recently acquired a fairly ancient packard bell PC and set about formatting the drive and installing Ubuntu on it, which was succesful. I now can't get into GRUB however as when I load the computer up, I'm presented with options to continue with the POST or to go into a CMOS menu. After this, the computer tries to boot from a CD and won't go any further.
Obviously I'd usually go into the BIOS and change the boot sequence, but I can't see any way of doing so. Any suggestions?
