You can always rebuild the grub mbr with grub itself.

#grub
>root (hd0,1)
>setup (hd0)
>quit

That assumes that linux is installed on the first drive "hd0" and /boot is
on the 2rd partition ",1"

No problem, Louis.  I'm glad it worked out for you.  Good persistence.
 Since the following contains a bunch of good Windows-Linux migration and

sorry for calling your message off-topic; I think Brian's right, that it was
on-topic, and I was being overly strict in my interpretation, as shown by
the return to topic.  Sorry...

Windows installs always destroy the GRUB MBR, overwriting it with a
Microsoft MBR that leads to the WinNT boot loader.  Unlike Linux setups,
Windows setups don't attempt to create boot options for foreign OS's already
present on the system.

I can show you at the next Installfest how to backup and restore the MBR
using dd, if you like.  It's usually something like this:

backup

  dd if=/dev/sda of=my-MBR-backup.dd bs=446 count=1

restore

  dd if=my-MBR-backup.dd of=/dev/sda

There's no need to control the block size on restore, because dd
automatically stops at the end of the input file.
