The Right Guide to MBR for Windows XP, Vista, 7, 8, 8.1, 10

In this tutorial, you will learn how to repair the Master Boot Record (MBR) on any of the Windows versions: Windows XP, Vista, 7, 8, 8.1 or 10.

What Is MBR

?

MBR (short for “Master Boot Record”) is the boot sector (hard disk area) that contains information about the partitions on the hard disk and acts as a boot loader for the operating system you are using ™.

The Master Boot Record is created when Windows is first installed on the first partition created. These are the first 512 bytes of your hard drive.

If the MBR is damaged, you will not be able to start Windows. All versions of Windows – Windows XP, Vista, 7 or 8 – use the MBR. If it’s damaged, you won’t be able to start.

It can be corrupted by some viruses that target the MBR to replace it with their own code, or in cases where you duplicate a Linux distribution (see Error: no section. Grub Rescue article).

Backup

You can back up your MBR by p Because it is stored on your hard drive, you can restore it later if necessary.

You only need one command to save the MBR:

 dd if = / dev / sda from = / backup path / mbr-backup bs = 512 count = 1 

In the above command, / path to save / mbr-backup is the path where you want to save mbr-backup .

Recover

Important! If you restore the master boot record with the wrong partition table, your data will become unreadable and very difficult to recover later.

You can restore a saved Master Boot Record with the following command:

 dd if = / path to restore / mbr backup from = / dev / sda bs = 512 count = 1 

In this command, / path-to-get / mbr-backup is the path where you saved mbr-backup .
