<pre wrap="">I checked 'edit' in grub and it seems to me that the 'kernel

best option is to load the 'server' kernel which is already installed;
then quickly enough I can get to a tty.

<pre wrap="">I am not sure what RAID is, so if I have it I didn't configure it
intentionally. I only have a SATA hard drive, on which I have a
logical /dev/sda3 partition which contains /dev/sda5 for /boot,
/dev/sda6 for / (root) and /dev/sda8 for /home. I always use a single
harddrive to boot.

"Should I run a more in depth SMART
test on the disks?" This may be helpful in order to work out what
area of the disk is actually causing the problem. Please could you
also give the output of <b>sudo fdisk -l /dev/sda</b>, this would
enable us to work out specifically which area of the disk is damaged
by comparing it to the sector read errors.
