etc/fstab Device label changed cant restore the default device name

hi,
I changed the label of the root partition in my etc/fstab....
Now when i rebooted the device is not identifiable and the kernel is providing a repair shell....to repair the system..
But when i tried to edit the "etc/fstab" file using vi editor the changes are not
saved because the shaell says the "fstab " is Read Only filesystem ...
even when i m in super user mode (i.e. root user mode)...
i tried changing the permissions by giving

root@localhost# chmod 777 etc/fstab

even then the permisiions are the same i.ei. readonly...
please tell me how can i restore my previous fstab file....

Try to remount your hard disk read-write:

Code:

mount -n -o remount,rw /

and then edit /etc/fstab

Becourse at boot time root partition is mounted in read-only mode for fsck to be able to check it, and then remounted in rw mode. Your error occures before filesystem whas remounted.
