Fixing Windows Boot Manager Error

Windows Boot Manager (BOOTMGR) is a small piece of software that helps your computer start up. If you encounter an error with BOOTMGR, it can prevent your computer from starting correctly. Fortunately, there are several methods you can use to fix this issue.

Method 1: Use the Windows Recovery Environment

The Windows Recovery Environment (WinRE) is a set of tools that can help you troubleshoot and repair common problems with your computer. To access WinRE, you will need to boot your computer from a Windows installation disc or USB drive. Once you have booted into WinRE, you can use the “Automatic Repair” tool to attempt to fix any issues with BOOTMGR.

Method 2: Use the Command Prompt

If the Automatic Repair tool does not work, you can try using the Command Prompt to manually repair BOOTMGR. To do this, boot your computer from a Windows installation disc or USB drive and then select “Repair Your Computer” when prompted. From here, select “Troubleshoot” > “Advanced Options” > “Command Prompt”. Once in the Command Prompt, type in the following commands:

  • bootrec /fixmbr
  • bootrec /fixboot
  • bootrec /scanos
  • bootrec /rebuildbcd

These commands should repair any issues with BOOTMGR and allow your computer to start correctly.
