History:
- computer arrives with Win2k installed on NTFS
- Shrink original partition and create 2 additional partitions using 
Partition Magic
- Install Win98 on FAT32 on one of the partitions so that Win2k provides 
choice between them
- Install RH 7.3 on the third partition, choosing to put GRUB in the MBR
- Now have computer that provides "Red Hat" and "DOS" choices in GRUB
- Choosing Red Hat boots Linux.  Cool.
- Choosing DOS brings up the Win2k boot menu, providing Win2k and Win98 
choices.
- Choosing Win98 there boots Win98.  Fine.
- Choosing Win2k there produces:
"Windows 2000 could not start because the following file is missing or 
corrupt: <windows 2000 root>/system32/ntoskrnl.exe.
Please re-install a copy of the above file."

I know I need to do "fdisk /mbr" from a Windows boot disk to get Win2k back 
alive (at least I am pretty sure that's what must be done).  But, what do I 
do after that to make the Linux partition selectable and bootable since 
that operation will wipe out GRUB?

At this point, it may be just as easy to re-install the Linux after fixing 
the Win2k boot problem.  I just wanted to learn how to do it without 
re-installing.
