Thread: Error on startup: 'Non-system disk or disk elTor'

When a computer fails to start and gives a blank screen with the above message, it's usually easy to fix. Check the floppy disk drive slot - if there's a disk inside, eject it then restart the computer.

If this doesn't fix the problem, unplug any storage devices such as USB memory keys and eject any CD discs before trying again. If the computer still cannot start, this could be the result of a more serious problem such as a loose cable or broken hard disk - we recommend seeking help from a technician.
