Win98 Bootup

How can I restore the bootup for Win98 without having to reinstall windows? I tried fdisk /mbr and it did not seem to work. I had a crash and tried restoring it, with Goback, and after it was “restored” I can’t get into win98 unless I use a startup diskette.

Use the boot diskette and run sys c: from it

If that dont work then scandisk and see if the boot sectors are bad.
