I have Ubuntu 12.04 by installed on my Inspiron N5030. Its my only operating system. Recently, ubuntu had a problem with resuming from hibernation. This has happened before, and I simply held the power button until the system shut down and restarted without a problem. Now I did the same thing once again, except this time, my system wont boot. Could I have damaged ubuntu by shutting my computer off manually? Is there anything I can do to fix it? I'd really rather not lose all my data.
