View Full Version : [ubuntu] Ubuntu 12.04 crash

October 7th, 2012, 06:59 AM
Hi I have a dual boot with win7 and ubuntu 12.04. Last night some UPS failure caused the system to crash without going through the entire shutdown process.When I rebooted Ubuntu it shows a dark screen with message like:-
dev/sda3 failed to unmount cleanly...
sulogin:cannot open password database

and restarts all over...

I read :- this link (http://ubuntuforums.org/showthread.php?t=1917124) but dont understand how do I mount /etc from the live cd.

Gone fishing
