As my first totally linux system, i've been running lubuntu 12.04 on a lenovo x120e with an OCZ vertex 60gb SSD switched out in place of the stock HDD for some time now with no major problems (other than the wifi card, but i've read that is pretty standard with this setup). The other week I was in the middle of a typical update when it said that there was an error with the program. I exited out of the window and noticed that my background was totally black, and my desktop icons weren't visible. I (with little forethought) decided to reboot, at which point I was unable to even get GRUB to load. The computer reaches its initial startup screen after the lenovo logo appears, at which point it states "No boot filename found, exiting PXE MOF." The screen then goes totally black for several moments before simply stating "No operating system found." I have to hold down the power button for a hard shutdown to get the computer to leave this screen.
After researching for similar problems, I came across the boot-repair program, and thought this could help. I loaded the ubuntu secure remix that contains it onto a live usb and ran the diagnostic, which stated that my boot was successfully repaired. The same sequence I described above still happens upon startup. Here is the pastebin log of the occurence.
As of right now, the only way I can use my computer is while using a live usb.
Normally i'd just wipe the system and do a fresh install because I back my data up weekly and try not to keep a whole lot stored on the actual HD, but there's a few important pieces of academic work I can't afford to lose that were only on the HD during the fated week in question. With the quarter coming to a close, that work is becoming more and more necessary to have.
If there's any advice you all could offer to help me at least recover the data, let alone restore the system, i'd be incredibly grateful.
