BEFORE you format your C: Drive.

Are you using a boot disk that was created with Win98 SE? If so, there's an easy way to put on the Command.com files again and make the C: drive bootable once again, without formatting. At the prompt type in sys C: so your screen will look like:

A:\>sys C:

If you have a proper boot disk, this will copy the system files over to the C: drive and make it bootable, at least into DOS. This will NOT format the drive and destroy any information. If you cannot boot into windows at all after this then you may need to re-install windows. Again, a format is NOT necessary.

I hope I was able to get this to you soon enough before you trash the info on the drive. If not, hope you have backups.

At any rate, good luck!
