Grub Rescue No such partition, No command except ls and set working
 

Hi
I have both windows7 and Linux 10.04 installed in my system. The problem occurred on a forced shut down.
The message which is appearing on the screen is
grub rescue
No such partition

No command other than ls and set are working. Set shows root to be in (hd0,6). ls is not listing (hd0,6)
The ls is not able to read any of the partition it lists and shows error:unknown file system.

Please help

Linux 10.04--is that Ubuntu Linux 10.04?

You should be able to boot the installation cd as a liveCD.

Please show the output of the following:

1) sudo fdisk -l
That will show the partitions that are found when the liveCD boots up.

2) sudo less /boot/grub/menu.lst (or sudo less /boot/grub/grub.conf is you are using grub 2).
That will show the configuration of your grub setup. A discrepancy between the two outputs should help solve the problem.
