If you have a lost partition or strange problem with your hard disk partitions, run TestDisk to recover your data. TestDisk can also undelete files from FAT, NTFS, exFAT and ext2 filesystem.To recover your lost digital pictures or lost files, try PhotoRec.
BIOS setup can be password protected. You can get back your password with CmosPwd.
(Personally, I would go for the password reset jumper.)
