I've been running Win 7 along side ubuntu for a few months now with any problems. Getting the dualboot to work was a bit tricky and required some modifications of the boodloader.

Today, Win7 comes to a near halt and I hard restarted the laptop. Upon restarting I was met with options to repair startup problems. Needless to say, Win7 is no longer working. After modifying the bootloader startup repair can no longer find the OS.

But the real problem is now in ubuntu, before I had three drives visible (OS, Recovery and DATA). Now, I only have OS visible but when I click it returns "Unable to mount OS". I am not able to save any files nor login as root do to the fact that my computer is "unable to find XAuth file".

I've done some searching but I can't find a solution specific to this problem. Advice is appreciated.
