When to Suspect Hard Disk Failure?
When you get OS not found error problem due to hard disk failure first you need to check floppy disk drive or any other external drive attached to the system. Is there a disk in it? If yes then just remove the floppy disk from your computer will probably solve the problem. Your computer may have been looking for an OS on the floppy, and as a result, you are getting an error message. Just removing the floppy disk should fix your problem.
If there is no floppy disk in your computer drive, now it is the time to check the computer boot sequence. You can easily do this in your BIOS. First of all, you need to check does your hard disk drive get detected as the main hard disk drive? If it doesn’t, your hard disk may have failed. If it does, move to the Boot Sequence section of the BIOS. If your hard disk drive doesn’t show up within the first three boot devices, you probably have a problem. Regulate your BIOS consequently.
If you have completed these initial checks, and still receiving the OS not found error, your hard disk drive has been failed. But DO NOT PANIC. Your hard drive data can be recovered by a professional data recovery firm.
