Backup your MBR

September 5, 2011 by Igor Drobot Leave a Comment

Master Boot Record (MBR), a small program that is executed when a computer boots up.

You can save your MBR with a simple DD-command to a file:

1
dd if=/dev/sda count=1 bs=512 > /var/backup/MBR

dd if=/dev/sda count=1 bs=512 > /var/backup/MBR

From this file you can restore your MBR very easy:

1
dd if=/var/backup/MBR of=/dev/sdb

dd if=/var/backup/MBR of=/dev/sdb
