Ubuntu halts after few seconds of starting and nothing works command, virtual terminal, GUI

I installed ubuntu and after a fresh restart the sysyem goes to halt. It shows following error in the virtual terminal
[484.269470] EXT4-fs error (device sda1): ext4_find_entry:1309: inode #2093097: comm dconf-service: reading directory lblock 0

Solution 1:

Looking at the output from the terminal, it seems there's some problem with partition inodes, you should try below:-

NOTE:- fsck/e2fsck works on unmounted partitions, so you first need to boot to recovery, and then run fsck from there by the option given or by dropping running to root shell prompt and then running the below commands.

Run:

umount /path/to/device
fsck -t ext3 /dev/whatever 

followed by:

e2fsck -f /dev/whatever

EDIT:-

This and this will probably help you alot!
