In this short tutorial we will see a helpful tip for backing up the system MBR (Master Boot Record) via the command line in Ubuntu (12.04/11.10). MBR is usually located in the first sector of the hard disk or other data storage device that holds the partition table. If you want to make some modifications to the boot loader, commonly known as the GRUB boot loader in Ubuntu, make a copy of the MBR would be highly recommended so you can restore it in case of unexpected problems, especially when doing a dual boot.
We assume that the hard disk is / dev / sda. If not, then you can replace it yourself in order below. We will use the DD command line tool to copy the MBR. Open a terminal and run this command to backup MBR:

sudo dd if=/dev/sda of=boot.bin bs=512 count=1

A "boot.bin" file will be created at the location of the current terminal. Move this file to a safe place on your disk or USB stick. Then, you can restore the MBR with the command:

sudo dd if=boot.bin of=/dev/sda bs=512 count=1
