Iv been researching for 2/3 days about this problem and i have came up empty.
Basically, partition 1 is windows 7 and partition 2 is ubuntu 12.04.
I told ubuntu (when installing to partition 2) to install grub on partition 1, and that works fine.

I am running 12.04 in a dual boot configuration with W7. Installation has been stable since May 2012; however, three times over the past four weeks and twice in the last two days I have received the message "Unable to find any bootable devices" when booting up the computer.
I'm running ubuntu 14.04 on my laptop and today my boot became corrupted. I have tried using the boot repair program from a LiveCD to no avail. I would try to just grab my documents and to a full reinstall, but the hard drive won't let me in (even after I give my admin password). So I'm kinda stuck at the moment.
