How to Repair the Windows 11 Bootloader

Windows 11 users sometimes encounter boot issues caused by a damaged bootloader. This can happen for various reasons, such as after an update, installation of third-party software, or changes to the system configuration. In this article, we’ll go over how to repair the Windows 11 bootloader using built-in system tools and a bootable USB drive.

1. Using Automatic System Repair

Windows 11 provides an automatic repair tool to fix boot issues, accessible through the recovery menu. To use this method, follow these steps:

  1. Restart your computer and repeatedly press F11 (or Esc depending on your device) to enter the Windows Recovery mode.
  2. Go to Troubleshoot → Advanced Options → Startup Repair.
  3. Select your account, enter your password if required, and then click Continue.
  4. The system will automatically attempt to fix bootloader errors.

2. Repairing the Bootloader via Command Prompt

If automatic repair doesn’t resolve the issue, try using the Command Prompt. You’ll need a bootable USB drive with Windows 11. Here’s how:

  1. Connect the USB drive and boot from it.
  2. On the installation screen, select Repair your computer in the bottom left corner.
  3. Navigate to Troubleshoot → Advanced Options → Command Prompt.
  4. Enter the following commands, pressing Enter after each:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands will overwrite the boot record and repair any damaged bootloader files.

3. Checking Disk and System Files

Repairing the bootloader may require checking the integrity of system files and the hard drive. Run the following commands in Command Prompt:

sfc /scannow
chkdsk /f /r C:

The first command scans and repairs system files, while the second checks the disk for errors and fixes them.

4. Reinstalling Windows 11 as a Last Resort

If none of the above methods work, reinstalling the operating system might be necessary. Remember that this could erase your data, so back up important files if possible.
