Someone else used my inspiron 510m and now when i turn it on i get "loading PBR for descriptor 2...failed." When I press a few random keys I get "No bootable devices--strike F1 to retry boot, F2 for setup utility"
I havn't got a clue what to do, and I'm useless with computers.
It sounds like he may have disabled your bootable drives in BIOS on Page 2. The Boot Order can be modified to move drives around, but it is also possible to disable them; they then willl not work no matter where they are in the Boot Order. On my I8200, you enable and disable them by highlighting them and then using the space bar. The Instructions for your model should be in the right column after highlighting the drive; your owner's manual only says it is possible , not specifically how to do it.
