Symptoms of MBR corruption

MBR (Master Boot Record) is a default record created automatically when you install Windows. It holds valid information about your hard drive partitions, and it plays an important role during booting. Hence, when the MBR is corrupted, your PC will find it difficult to boot properly.

But what are the signs that indicate your system’s MBR is corrupted?

Most often, when you get any of these error messages, it could be that your system’s MBR has corrupted:

  • Error loading operating system
  • No bootable medium found
  • Invalid partition table
  • Operating System not found
  • Reboot and select the proper boot device

How to fix this issue

Here you will find 3 great methods and any of them can be helpful for you.

Method 1: Fix MBR using Command Prompt on Windows 10

This method is for Windows 10 users. You will need Windows installation media or a recovery drive to follow the steps below.

  • Insert the Windows Installation Media or Recovery Drive and boot from it.
  • When the PC boots up, you’d find a "Repair your computer" link at the bottom area.
  • Click on the link, go to Troubleshoot, and then Command Prompt.
  • When Command Prompt opens, run these commands in order:
  • Remember to hit the Enter key after typing each of the commands.
  • Close Command Prompt after running the last command.
  • Restart the computer normally (don’t boot from the recovery drive or installation media).

Method 2: Use Command Prompt to fix MBR on Windows 8

The steps are the same as what's explained above; however, for this method, you need Windows 8 installation media.

  • Insert the Windows Installation Media or Recovery Drive and boot from it.
  • When the PC boots up, you’d find a "Repair your computer" link at the bottom area.
  • Click on the link, go to Troubleshoot, and then Command Prompt.
  • When Command Prompt opens, run these commands in order:
  • Remember to hit the Enter key after typing each of the commands.
  • Close Command Prompt after running the last command.
  • Restart the computer normally (don’t boot from the recovery drive or installation media).

Method 3: Fix MBR on Windows 7

For Windows 7 PCs, you need Windows installation media for Windows 7 or a recovery drive created with the PC prior.

  • Insert the installation media and boot from it.
  • You’ll get a quick notification to “Press any key to boot from DVD”.
  • Choose the language and keyboard layout.
  • Click "Next" to continue.
  • Select the Operating System and click "Next" again (check "Use recovery tools that can help fix problems starting Windows").
  • Get into “System Recovery Options” and select "Command Prompt".
  • When Command Prompt opens, run these commands serially:
  • Remember to hit the Enter key after typing each of the commands.
  • Close Command Prompt after running the last command.
  • Restart the computer normally (don’t boot from the recovery drive or installation media).
