Ubuntu 9.04 doesn't boot anymore - No init found


Hi there,
Friday a have shut down my working Ubuntu 9.04 for many months, and now, after 2 days, i keep receiving the folowing output when it boots up?
kinit: trying to resume from /dev/disk/...
kiniy: no image to resume, doing normal boot
mount: mounting /dev/disk/by-uuid/...some hex numbers... on root failed: Invalid argument
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesnt have /sbin/init
No init found. Try passing init=bootarg
BusyBox v1.10.2 built-in shell
(initramfs)_

I google it a little and it seems that grub somehow got coruppted. I have found some suggestions on how to fix this:
"Boot from the Live CD.
Run sudo fdisk -l The output will be will be a list of your partitions which you need to identify your root partition (usually this is sda1)
You need to mount that partition to access the files:
sudo mkdir /media/root
sudo mount /dev/sda1 /media/root
Browse to /media/root/boot/grub and look at menu.lst and make sure that references the correct sda# value.
Browse to /media/root/etc/ and look at fstab and see if the values are correct (you can also replace the uuid values with the sda# values in the comments)"

.....BUT
when i try to mound sda5 in my case it sais:
ubuntu@ubuntu:~$ sudo fdisk -l

Disk /dev/sda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

ubuntu@ubuntu:~$ sudo mount /dev/sda5 /media/root/
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5

Disk /dev/sda5: 15.0 GB, 15002878464 bytes
255 heads, 63 sectors/track, 1823 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/sda5 doesn't contain a valid partition table

Now, this last errorDisk /dev/sda5 doesn't contain a valid partition table) i don't know how to fix it, so please, can anyone guide me on how to get my working Ubuntu back?
