Ubuntu 9.10 Boot Failure

I am a linux newbie, I have been using ubuntu with no major problems for 1 month, until two days ago i had a boot failure and havn't been able to resolve it upto to this moment.

I am stuck at this point with no clue how to proceed. I have done a lot of research in linux forums and therefore i have collected some information about the error which could be helpful:

The error message is:

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (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/bd4d1516-41d3-4fe1-97b2-398c355683bc does not exist . Dropping to a shell!
I have used my ubuntu installation cd and ran the try ubuntu option and typed the following commands in the ubuntu terminal.

Typing cat /etc/fstab, i get:

aufs / aufs rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda5 swap swap defaults 0 0
Typing sudo fdisk -l, i get:

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

I hope anyone out here can help with this issue.

Thank you in advance

Hi surfbear.

This problem is way over my head but...

Are you dual-booting with Windows? If so, does Windows boot?

Also what hardware are you using?

Could you please post the output of sudo lshw?

Thank you.

Ubuntu 9.10 still using GRUb 1 I think .
If so post the menu.lst .
You can find it at /boot/grub/menu.lst
If you use GRUB 2 you have a grub.cfg .
You find it at /boot/grub/GRub.cfg
Also use the commmand sudo su ls -l /disk/dev/by-uuid
Post you're menu.lst and the outcome the command I give you
