View Full Version : [ubuntu] LiveCD could not mount hard disk, and RESULT.txt file from Boot Info Script

I have a Ubuntu 12.04 desktop (solo Ubuntu only), and recently due to my son's mistake, it could not reboot again. So I used my LiveCD but could not mount to the computer Hard Disk. I checked the webage and found the script (http://bootinfoscript.sourceforge.net (http://bootinfoscript.sourceforge.net/)) and ran it and the results were listed below. Could anyone having this experience help me re buit my GRUB and rescue my computer?

THanks,
Bruce

It looks like script cannot mount sda6 which grub is trying to boot from. I then assume that is you main install.

Try this from liveCD.

#From liveCD so everything is unmounted,swap off if necessary, change example shown with partition sda6 to your partition(s)
#e2fsck is used to check the ext2/ext3/ext4 family of file systems. -p trys fixes where response not required
sudo e2fsck -C0 -p -f -v /dev/sda6
#if errors: -y auto answers yes for fixes needing response see man e2fsck
sudo e2fsck -f -y -v /dev/sda6
