Boot grub menu list is accidentally removed from Ubuntu Jaunty and sysem boots to gru

Sir,
I am not much experienced with Linux systems and commands. I have been searching with Goggle and trying to solve. Today I had accidentally removed the boot grub menu list. There is a backup file. Now my system boots to >grub command. I have tried all sorts of things from live CD to boot the system I have tried Super Grub also. I am no able to go to the directory where the back up boot menu list is available and change the name from the live CD. Can any one help me with commands to go to the directory and rename the file for booting . Thanks in advance.

welcome to LQ!!

Boot up from a live CD and open a terminal. Then do this: (I am assuming the the Ubuntu /boot directory is on sda1 (ie the first partition of the first drive.) I'm also assuming that the backup file is "menu.lst.bak".

Code:

cd /mnt

mkdir ubuntu

mount /dev/sda1 ubuntu  ##change sda1 if required

cd ubuntu

cd boot/grub

ls    ##check the name of the backup file

cp menu.lst.bak menu.lst

reboot

Sir,

I am very grateful for the solution. Since I am with Ubuntu Jaunty, my old Super Grub did not work. I have made a CD with the latest updated suitable for Ubuntu 9.04 with ext4 this had solved the problem. How ever for my knowledge improvement I have tried your solution with live CD. I have learnt to day : how to get into files with cd command from live CD. My backup menu.list is :menu.lst.backup". Let me thank you once again. Hope this thread will be helpful to many.
