The MBR (Master Boot Record) controls where the PC boots off and is thus vital for a computer’s well-being.

That’s why we’ve put together a list of solutions for you to try to resolve your missing MBR problem, so keep reading.

What should I do if my MBR isn’t there?

1. Restart your PC

Your PC’s inability to recognize your MBR may be simply the consequence of a chance occurrence.

As a result, when an error warning displays, simply follow the on-screen directions to restart the computer. If this doesn’t work, you should go to the next solution.

2. Remove all removable media from your computer

Removing any portable media will compel the PC to boot from its hard drive, as the MBR decides where the PC boots from.

This includes disconnecting all CDs, DVDs, and detachable flash drives before restarting the computer.

3. In your BIOS, change the boot order

  1. Enter the BIOS after turning on your computer.
  2. Change the boot order such that the hard disk containing the MBR is the first option in the Boot tab.
  3. Exit after saving the changes.

4. Repair your Master Boot Record

  1. Create a bootable USB flash drive or CD/DVD with MiniTool Partition Wizard.
  2. Place the removable media in the computer.
  3. Change the boot order of the computer to start from the removable media.
  4. To begin, open the Partition Wizard.
  5. From Check Disk, choose the damaged disk and click Rebuild MBR.
  6. Select Apply and wait for the software to finish.

A highly damaged MBR can sometimes generate the missing MBR error. If this appears to be the case, you will need to make repairs.

You might try using MiniTool Partition Wizard, a professional third-party utility, and then follow the following procedures.

5. Set the partition to active mode

  1. Steps 1-3 from the previous solution should be repeated.
  2. Select the incorrect active partition and press the Set Inactive button.
  3. Select the partition you require and click Set Active.
  4. Allow the program to run its course before pressing Apply.

6. Run a hard drive test

  1. To access the MiniTool PE Loader interface, follow the instructions outlined above.
  2. Select the Surface Test option and wait for the program to finish.
  3. Restart the computer.

Too many faulty sectors on the drive are a common cause of the missing MBR problem.

MiniTool Partition Wizard comes to the rescue once more, as it includes tools for testing the disk surface of a drive.

7. Run a startup repair on Windows

  1. Create a bootable USB flash drive or CD/DVD with your OS.
  2. It’ll take you to the Advanced boot settings menu.
  3. Select Advanced Options from the Troubleshoot menu.
  4. Select Startup Repair as your option.

8. Examine your cables

The missing MBR issue might be caused by something as simple as old, broken, or poorly plugged connections.

As a result, turn off your computer, double-check that all cables are plugged in, or even try replacing them with new ones (especially the IDE cable).

9. Make sure your motherboard’s operating system is up to date

An outdated BIOS version might also cause a missing MBR issue. Thus, upgrading your BIOS to the newest accessible version is always good. Check out our thorough instructions if you don’t know how to accomplish this.

10. Install Windows from scratch

If none of the other 9 solutions worked, your only option is to reinstall Windows from scratch.

Keep in mind that this will erase everything from your computer, so make a backup of all of your data before attempting this approach.

11. Get a new hard drive

If the missing MBR problem appears to be caused by a cluster of damaged sectors that no amount of Windows cleaning can solve, it’s time to retire your hard drive and replace it with a new one.

While this is the most expensive option, it is the only one that will guarantee the removal of any missing MBR issues.

Because this is such a significant investment, you should look for the best hard drive that your budget will allow.
