Back up MBR

Back up the Master Boot Record

This page was last updated on August 18, 2013.

Replace /dev/sda with your device (if you don’t know which device your system is on, you can open the KDE Partition Manager in the System folder of the menu, look at a list of your devices, and then close the program) and /path/filename with the path and filename of the file you want to create.

1. Back up the MBR:

dd if=/dev/sda of=/path/filename bs=512 count=1

2. Restore MBR:

dd if=/path/filename of=/dev/sda bs=512 count=1

Obligatory Happy Ending

And they all lived happily ever after. The end.
