started my comp this morning, and came up with error 00057.....or something like that. trying to f-disk, but keeps asking me for diskette in A:drive, no matter what i change boot location to in BIOS.
Did you have Windows set to do an automatic update by any chance?
Oh, and for the bios thing, you might want to clear cmos.
I hope you understand that you cannot format the drive with OS on it uless you start computer form other drive.Changing BIOS start sequence will not help if main OS disc is corrupted or faulty.
