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.
