I think I've lost my MBR upgrading from ubuntu 10.04 to 10.10.
During the upgrade it gave me a message saying which partitions did I want the grub details to go on, saying if I was unsure to select all of them.
After reboot I just end up in a grub recovery console.
The system was a dual boot with windows vista.
Any Idea how I can get both my operating systems to work?
I'm currently attempting to download a live cd of 10.10 but its a rather big download to fix what I assume is a small problem. Worse than that I don't have a clue how to fix it with the live CD.

http://ubuntuforums.org/showthread.php?t=1639198 by following the instructions on that page I was able to install lilo.
Lilo gives me two options ubuntu and windows. Windows works directly, choosing ubuntu brings me to grub which allows me to boot ubuntu.
Yes grub gives a warning about an invalid background colour but at least my machine is usable (or as usable as it was before.).
