I REALLY hope you guys can help me.
Straight up - I'm a normal user who has been enjoying Kubuntu for 2 years (and Ubuntu for 2 years before that). My knowledge of troubleshooting is basic but I am good at following instructions
My laptop (Acer Aspire 4750G) running Kubuntu was only last week successfully upgraded from 12.04 to 12.10. Current GRUB version is 0.97-29ubuntu66.
My laptop runs only Kubuntu.
Today, I had 'itchy-fingers' and decided to tick and update several ppa's which were automatically un-ticked during the 12.10 upgrade.
I ran the update on Muon. The update went well. The problem happened when I rebooted the laptop. The boot-splash screen apprears with the Kubuntu logo in the centre & 5 little dots. After that, the screen goes black and plain text appears on-screen showing some stuff booting. It stops at 'Check Battery'.
So, I switched off & on my laptop. Held down the <Shift> key to access the utility screen & selected 'Ubuntu Advanced Options'. I then selected 'Drop to root shell prompt'.
I found the below-post after some minutes checking the forum:

After reading 'SteveRileys' instructions, here's where I am now;
***TEST 1***
(In recovery mode & running in command-prompt)

Typed 'fsck /dev/sda'
fsck from util-linux 2.20.1

fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda2
Could this be a zero-length partition?
Typed 'fsck /dev/sda3,4,5,6'
fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)
fsck.ext2: No such file or directory while trying to open /dev/sda3
Possibly non-existent device?
***TEST 2***
Typed 'cat /etc/fstab'
(See 'Screenshot 1' for output)
Typed 'mount'
(See 'Screenshot 2' for output)
Typed 'cat /proc/mounts'
(See 'Screenshot 3' for output)
***TEST 3***
Typed 'mount -o remount,rw /'
(No output)
Typed 'dpkg --configure -a'
(No output)

PS : Apologies for starting a new thread for this but I didn't want to 'hijack' Shabakthanai's troubleshooting works on the thread he started ('Distribution upgrade from K12.04 to K12.10 64bit stopped at 68%').
