[vox-tech] boot failure with KDE

[Thomas Johnston]

Just to be painfully clear as to what I am doing:
(1) power on, hold down shift key
(2) highlight boot option, "Ubuntu, with Linux 2.6.32-22-generic
(recovery mode)" and press 'e' to edit the commands
(3) from the recovery menu, choose 'root' drop to root shell prompt
(4) I enter my root password and then run fsck /home, which gives the
following output:
# fsck /home
fsck from util-linux-ng 2.17.2
e2fsck 1.41.11  (14-Mar-2010)
fsck.ext2: Is a directory while trying to open /home

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the
superblock is corrupt, and you might try running e2fsck with an
alternate superblock: e2fsck –b 8193 <device>


I am not sure that this is relevant, but my /dev/sda1 is type ext4
