I did a clean install of Ubuntu 12 several months back on Toshiba Satellite laptop and have had no problems. System was up to date working great.
A couple days ago I tried the suspend option instead of shutting down and could not resume. Had to do a hard shutdown and now I can't reboot. All I see after GRUB is black screen with flashing cursor in upper left corner of screen.
Have seen many similar problems listed and tried many of the solutions suggested while booting from a live CD but still can't get to the root of the problem. I can try to run
fsck from LiveCD but my drive doesn't have multiple partitions (sda1, etc). I just let Ubuntu do a clean install and files are where they are.
