Linux – Ubuntu 6.06: Mounting /root/sda1 /root failed: No such device

An old machine in our office, running Ubuntu 6.06 all of a sudden will not boot up. I get the following info during boot:

Uncompressing Linux... Ok Booting the kernel
mount: Mounting /root/sda1 /root failed: No such device
mount: Mounting /root/dev on /dev/.static/dev failed: No such file or directory
mount: Mounting /sys /root/sys failed: No such file or directory
mount: Mounting /pro /root/pro failed: No such file or directory
Target filesystem doesn't have /sbin/init


Busybox v1.01 (debian 1:1.01-4ubuntu3) Built-in shell (ash)

Enter 'help' for a list of built-in commands
/bin/sh: can't access tty; job control turned off
#

I haven't changed anything on the system as far as I'm aware, and I ran some HD diagnostics and everything seems fine.

After Googling around, I found this thread: http://ubuntuforums.org/showthread.php?t=246895 Which seems very similar to my problem, however when I try to mount the drive with the following command:

sudo mount -t ext3 -o rw /dev/hda1 /mnt

I get the following error:

mount: wrong fs type, bad option, bad
superblock on /dev/sda1, missing code
page or helper program, or other error
In some cases useful info is found in
syslog – try dmesg | tail or so

I ran fdisk -l and it says the partition type is Linux.

The output after running dmesg | tail :

After running e2fsck -p /dev/sda1, I get the following info:

/dev/sda1: clean, 142449 / 9584640 files, 5402711 / 19161520 blocks

Now I'm really not sure where to go with this 😡

Thank you for looking
