How to recover Ubuntu when grub is gone ?

I was trying to resize my ubuntu 14.04 partion space using Gparted , where i deleted a partition which had my previous ubuntu install.

Unfortunately, the grub was loading from that partition and after my restart the computer went to the promt with grub rescue menu.

If you face the simillar situation , you can recover your OS grub loader as below.

This link was really helpful for me to boot my ubuntu installation .

Follow the steps given by Amr Amyan.

For me the commands were

set root=(hd0,msdos6)
set prefix=(hd0,msdos6)/boot/grub
insmod normal
normal

where msmod6 is the partition where ubuntu resides. That can be found by ls command .
Try ls(hd0,msdosX) and hit enter. you should be a valid partition . (ext2 partition)

But its not the end. You have just booted up the OS. When you restart you will be back to your grub rescue menu.

So here we have 2 options.

1. Using Live CD or Live USB
2. Using Existing Ubuntu

Since my Ubuntu 14.04 got booted up , i installed boot-repair from terminal by following these commands

sudo add-apt-repository ppa:kranich/cubuntu
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

Once its done , open boot repair and select “Recommended Repair” Menu . System will recover Grub and give you a link as well.
NOte down the link and restart your computer.

Bingo !!!!

Even after boot repair you are not getting the boot menu, paste the link to the corresponding email id. Ubuntu support team will help you out !!!.
