upgrade from ubuntu 12.04 to 12.10 failed, now loads "grub rescue"
- by Greg
I attempted to upgrade from 12.04 to 12.10 last night.  Installation seemed to go fine, and this morning I had a message like "restart now to complete installation".  So I restart, get an initial "Loading Operating System ..." message, followed by "error: file not found.  Then it kicks into "grub rescue" mode.  
Previously I have this running as a dual boot (window 7) and I just ran the upgrade to 12.10 via the update manager in ubuntu.  Any ideas on what is going on here, or what the error means?  I know my way around the command line, but this is above my pay grade.  Thanks for any advice.
