Bad news...it sounds like your hard drive is either dying or corrupted.

Here is what I would do first...Google "seatools" this is a set of software tools that you can use to test your hard drive. It's made by Seagate, but I've succesfully used it on other manufacturer's drives. Does you computer have a floppy drive? If not then you'll need to download the version of seatools that can be burned onto a CD. You'll also need software that will allow you to burn a "bootable" CD. If you don't have this capability and you don't have a floppy drive, then you're going to need to find someone who can burn the bootable CD for you.

Assuming you can get seatools put the CD (or floppy) in the computer and let follow the steps to let it test your hard drive. It's pretty straight forward.

If you're very lucky it may be able to fix your problems. If not you may need to reformat your hard drive or possibly you'll need a new hard drive.

If you have lots of important files on your computer that are not backed up then do not reformat the drive. Go buy a new one and install Windows on the new drive but also install the old drive. Many times the drive has problems that will prevent you from booting, but you can use it a bit longer as a second drive in the computer so you can recover your files.

I hope this all helps.

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; i.e. the device does not have bootable media. 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 seeks the floppy drive first and a non-bootable (or blank) floppy is in (was left in) the floppy drive. Other causes include:

No bootable partition on a hard disk drive

this message clearly shows that the hard drive on the computer has gone bad and you need to replace it.
