Fix error

Non-System Disk or Disk Error results when the Basic Input/Output System (BIOS) cannot find the boot sector or the master boot record is missing or damaged. Disk errors refer to common data corruption and to actual physical damage of the hard drive. The BIOS searches drives in the order usually specified in the CMOS Setup. This order is often, but not always, A: (floppy drive), C: (first partition on the hard disk)… The error will occur during startup if the CMOS is set so the BIOS seek the floppy drive first and a non-bootable (or blank) floppy is in the floppy drive. Other causes include:

• No bootable partition on a hard disk drive

• A defective hard disk drive

• The CMOS drive settings (parameters) are not correct for the boot device

• Defective floppy

• Defective floppy drive

• A virus
