FAT problem

Win98 se
2 ide drives, two partitions each.

I can't boot into windows, it goes to dos screen highlighting dos promt option.

I can't boot into safe mode either.

I booted off a floppy and tried to run scandisk.

Scandisk runs ok on all the partitions except for C:
Says it cant read the FAT.

I can read files on the c: from dos, so the drive is still there.

I tried booting from a norton 2001 cd and ran navdx.
It says boot record ok. I think its just checking it for virus.

Any ideas on how to fix the FAT?

I read this on another forum:
"If you are stuck in DOS... type - scandisk c: /autofix /nosave /nosummary - then hit the enter key. Then type fdisk /mbr <enter> to get FDISK to repair the Master Boot Record. "

Does that sound right or do I need some other software to repair the FAT?

Hope this helps but 98 isnt going to last long if its on the net anyway
