With your boot disk, type in "Format" and see if the format program starts.
If you want to see if your disk has patrons, type in "fdisk /status" this could give you HD information. Chances are, you will get the same error message as you got before, but its worth a shot.
Correction: You need to copy the Format file to your HD, and from what you have posted, this may be hard. If you get it copied, use this command while formatting "format /s" it will copy the system files and allow you to boot into DOS when your computer starts.
(Formatting erases your entire disk, it is hard to recover data, use as last resort)
(correct me if I'm wrong, I am not familiar with the commands "format" and "fdisk)
