This error is returned if the device part of a device- or full
file name refers to a disk or BIOS device that is not present or
not recognized by the BIOS in the system.




Power switched off and given again:

investigate your hard disk and/or bios. something didn't report
properly on booting. could be just a transient error, but more likely
the very beginnings of a hardware problem with a hard-drick controller
or a disk itself.
