I suggest you run fsck on the partition(s) and use smartmontools smartctl -a /dev/sda or smartctl -H /dev/sda change sda to your hard drive –bodhi.zazen Nov 18 '14 at 2:10 I have 2 external HDD's.

Boot with the live CD and remove all references to it from /etc/fstab (comment them out!) and see if you have enough of a system remaining to boot up!
