I did the exact same thing once - but there is a way to recover.
Do you have a Windows boot disk? If so, boot the computer
into DOS with it and at the prompt simply type 'SYS c:\'
(I'm assuming any reasonable DOS boot disk has sys on it).
That will rewrite the boot sector of the C:\ partition with
the DOS/Windows bootloader. Caveat: This was with Win95, not
Win98, but I don't see why it shouldn't still work.
The sys command will install msdos.sys, io.sys, and command.com to the
partition. It will not fix the mbr and it will mess up the win98
install. It's intended to make bootable floppies, if you do it to the C:
drive then the C: drive will only boot into the command prompt & you'll
have to reinstall windows unless you know some tricks.
I recommend, on the basis of 10 yrs QA lab experience:
1. Boot from an ms-dos floppy (e.g., win95/98/Me startup disk) and make
sure the desired partition mounts as the C: drive.
2. Run fdisk and make sure that the C: partition is marked Active.
3. From the dos command prompt, run
This is an undocumented feature of the fdisk utility that
repairs/restores the master boot record to the way microsoft thinks it
4. Power off & back on, any ms-dos/windows OS installed to drive C:
should boot OK.
I really don't want to be rude here but his problem isn't
with the harddisk's mbr - he made that quite clear in his
post - 'fdisk /mbr' will do nothing other than purge his
harddrive's mbr of grub, which is not what he wants to do.
What he has done is that he also installed grub in the boot
sector of his Win98 *partition* - that is, from a grub
command line he typed 'setup (hd0,0)' (or install) rather
than 'setup (hd0)'. It's this that he wants to fix. I did
the exact same thing one time by accident as I got my
harddrives mixed up. But I was able to use my Win95 boot
disk and type 'sys c:' at the DOS prompt and I can now boot
into Windows 95 again. I am not making this up...
