ubuntu 8.10 upgradation error.

[pinku80]

Hi,
After I upgraded ubuntu 8.10 and installing the updates I am unable to log in to my system after restart. This is the following problem I'm having.

Boot from (hd0,9) ext3 9557a59a- ff9f -451b -95cd –b51fcd5c99dc

Starting up…
Loading, please wait…
usplash: Setting mode 1152×864 failed
usplash: Using mode 1024×768
Gave up waiting for root device. Common problems:
- Boot args (cat/proc/cmdline)
-Check root delay= (did the system wait long enough?)
-Check root= (did the system wait for the right device?)
- Missing modules (cat/proc/modules; ls/dev)
ALERT! /dev/disk/by-uuid/9557a59a- ff9f -451b -95cd –b51fcd5c99dc does not exist. Dropping to a shell!

BusyBox v1.10.2 (ubuntu1:1.10.2-2ubuntu7) built-in shell(ash)

Enter ‘help’ for a list of built-in commands.

Please help me out with the problem.

The upgrade must have messed up the UUIDs of the disk or something. Try booting off a Ubuntu livecd and running:


sudo fdisk -l

Note down the /dev/sd* or hd* of the Linux boot partition (probably the same one as the root partition). From here on I'm referring to the boot partition as /dev/sda1, of course change it for your setup. Now, mount the partition like so:


sudo mkdir /mnt/disk && sudo mount /dev/sda1 /mnt/disk

If it mounts successfuly, continue (use gedit instead of nano for a graphical editor):


sudo nano /mnt/disk/boot/grub/menu.lst

Now, scroll down to where all the boot entries are, and at the bottom add your own one - I'm referring to the partition as hd0,0 but change it for your setup. In grub language, hd0,0 means /dev/sda1 or /dev/hda1, hd1,3 means /dev/sdb4 or /dev/hdb4, etc.:


title Ubuntu 9.04 test grub entry
root (hd0,0)
kernel /boot/vmlinuz-(whatever your kernel is) ro splash vga=791
initrd /boot/initrd.img(kernel version)
quiet

Now reboot and test the new grub entry.

when I'm using the code:

sudo fdisk-1

It's showing
/bin/sh:sudo: not found

what to do?

what to do?
sudo fdisk -l is with a lowercase L not the number 1, also make sure there is a space between fdisk and -l
