<p>You can always rebuild the grub mbr with grub itself.</p>

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

I'm glad it worked out for you. Good persistence. Since the following contains a bunch of good Windows-Linux migration and coexistence info, I hope you won't mind if I send it out onto the list. I'm 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...<br>

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.<br>
<br>
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:<br>
<br>
backup<br>
<br>
dd if=/dev/sda of=my-MBR-backup.dd bs=446 count=1<br>
<br>
restore<br>
<br>
dd if=my-MBR-backup.dd of=/dev/sda<br>
<br>
There's no need to control the block size on restore, because dd automatically stops at the end of the input file.<br>
