Unhappy Kernel panic message on boot

Hello, and Help!
Everything was running fine yesterday, this morning on booting I got this message:
[ 28.272109] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
right after the "Uncompressing Linux... Ok, booting the kernel" message.
I'm a newbie - do any of you experienced types out there know what I should do?

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
This means that your kernel looks for its root partition on in a place where there is none.

At a quick glance there are two possibilities as to what happened :

1)Your partition died; thus you kernel can't mount it.

2)Your menu.lst/lilo.conf got modified, and the kernel tries to read the wrong partition.

Are you using LILO or GRUB? If its GRUB, press "e" when given the choice to boot, and modify the "root=/dev/**** " section accordingly to your partition table (**** being the device and partition on which root is. e.g. /dev/sda2).

Else, you can download any LiveCD (knoppix for example), try mounting the partition, and modifying menu.lst/lilo.conf accordingly.

If you need more help, post menu.lst/lilo.conf here, as well as your partition table.
#fdisk /dev/****
(don't write the *)

kernel panic

Thank you for responding and for your advice. Further enquiries have narrowed the problem down to corrupted update the previous day. I have reinstalled.
Thanks again, your help much appreciated.

While re-installing is good practice , you may not have needed to do that. See this thread:
