How to repair MBR in Windows 11, 10, 8, 7

Here we provide two effective ways to repair MBR as the following content shows.

Qiling Disk Master Professional is a powerful MBR repair utility that can rebuild MBR, clone hard disks and partitions, convert MBR to GPT and vice versa, all while providing a "Recover Data" function in case of data loss.

With the feature Rebuild MBR in Qiling Disk Master Professional, you can easily repair damaged MBR within simple steps. This process involves a straightforward procedure where the software takes care of the entire operation, allowing users to quickly and effectively recover from MBR damage.

Before you do:

Connect the hard drive to a working Windows PC that has Qiling Disk Master installed, which can be downloaded from the official website of Qiling Disk Master Professional.

To create a bootable media using Qiling Disk Master, follow these steps: First, download and install Qiling Disk Master on your computer. Next, insert a USB drive or CD/DVD into your computer.

Step 3. After making the necessary changes, click "Proceed" on the toolbar to commit the Rebuild MBR operation.

Notes:
Rebuilding the Master Boot Record (MBR) is a lossless data operation, but if done incorrectly, it can render your computer unbootable. Therefore, it's recommended to gain a deeper understanding of the process before attempting it.
The "Rebuild MBR" feature can only fix issues related to corrupted MBR code, and is not a solution for problems caused by the loss of bootable or system files, which can prevent the operating system from booting.

▶ Method 2. Repair MBR via Windows Installation Disk

This method is more suitable for experienced computer specialists to use command parameters. If you can't boot the OS, you'll need to boot the Windows computer using the installation DVD. If you don't have a Windows installation disk, you can use a tool like Qiling Disk Master to create one.

If you have it, you can repair MBR easily. Below is an example of repairing the MBR in Windows using CMD:

Step 1. Connect an external disk to your computer, shut down the machine, and insert the installation disk. Boot from the disc.

Step 2. Select the time, language, and keyboard input, and click next.

Step 3. After that, click Repair your computer in the lower-left corner.

Step 4. Press Shift + F10 key combination to call out Command Prompt.

Step 5. Type the drive letter of your external hard drive partition at the prompt, like F: , followed by a colon and press Enter.

Step 6. Type these commands in sequence and press Enter after each.

● Bootrec /fixmbr
