In this article, we’re going to provide a step-by-step guide on how to fix MBR errors in Windows 10. We’ll cover the various methods available, as well as how to make sure your MBR is healthy and running properly. So if you’re ready to get started, let’s jump right in!

What is the MBR?

The Master Boot Record (MBR) is the information in the first sector of any hard disk or diskette that identifies how and where an operating system is located so that it can be bootstrapped (loaded into the computer’s main storage or memory). It is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond. The MBR holds the information on how the logical partitions, containing file systems, are organized on that medium.

The MBR code is usually executed (bootstrapped) by the PC’s BIOS ROM on system start up, which transfers control to the MBR. MBR also contains executable code to function as a loader for the installed operating system (usually by passing control over to the loader’s second stage). The MBR is created when a computer is partitioned and contains information about the disk geometry and the partitions’ locations.

How to Fix MBR in Windows 10?

If the MBR of your Windows 10 computer has got corrupted or damaged, you can easily fix it by using the Windows 10 installation media. You can also use the bootrec.exe tool to fix the MBR. Let’s look at both solutions in detail.

Using Windows 10 Installation Media

The first step is to insert the Windows 10 installation media into the computer. Make sure to use the same version of Windows 10 that is installed on the computer. When the installation media is ready, restart the computer and press the boot key to open the boot menu. Select the boot device that has the installation media and press the Enter key.

When the Windows 10 setup screen appears, select the Repair your computer option. Select the Troubleshoot option and select Advanced options. Select Command Prompt and type the following commands:

Bootrec.exe /FixMbr
Bootrec.exe /FixBoot
Bootrec.exe /ScanOs
Bootrec.exe /RebuildBcd

Using the Bootrec.exe Tool

If you don’t have access to the Windows 10 installation media, you can fix the MBR by using the Bootrec.exe tool. To do this, you need to boot into the Recovery Environment. To do this, restart the computer and press the boot key to open the boot menu. Select the boot device that has the Recovery Environment and press the Enter key.

In the Recovery Environment, select Troubleshoot and select Command Prompt. In the Command Prompt, type the following commands:

Bootrec.exe /FixMbr
Bootrec.exe /FixBoot
Bootrec.exe /ScanOs
Bootrec.exe /RebuildBcd

Using the Bootsect.exe Tool

If you are using Windows 7, you can use the Bootsect.exe tool to fix the MBR. To do this, boot into the Recovery Environment. Select Troubleshoot and select Command Prompt. Type the following command:

Bootsect.exe /NT60 All

Verifying the MBR Repair

After repairing the MBR, you should verify that the repair was successful. To do this, in the Command Prompt, type the following command:

Bootrec.exe /ScanOs

If the command returns a message saying that no operating systems were found, the repair was not successful and you need to try again.
