Step-by-step tutorial on Fixing Windows Boot Manager Windows 10
In this section, you’ll find a detailed and comprehensive guide to fixing Windows Boot Manager issues. Follow these steps carefully, and you should be back up and running in no time.
Step 1: Create Windows Installation Media
First, create a Windows installation media using a USB drive or DVD.
You’ll need another working computer to download the Windows 10 installation tool and create the media. Make sure your USB drive has at least 8GB of free space. This media will help you access repair tools.
Step 2: Boot from Installation Media
Next, insert the installation media into your computer and restart it.
You may need to change the boot order in your BIOS settings to boot from the USB or DVD. Press the appropriate key (usually F2, F12, ESC, or DEL) to enter the BIOS menu. Save your changes and restart.
Step 3: Access Repair Options
Once the system boots from the media, choose your language preferences and click “Next.”
Click the “Repair your computer” option on the bottom left of the screen. This will take you to the Windows Recovery Environment (WinRE), where you’ll find useful troubleshooting tools.
Step 4: Open Command Prompt
In the WinRE menu, select “Troubleshoot,” then “Advanced options,” and finally “Command Prompt.”
The Command Prompt is a powerful tool for fixing boot issues. It allows you to run specific commands that can repair the boot manager.
Step 5: Run Bootrec Commands
Type and execute the following commands one by one: bootrec /fixmbr, bootrec /fixboot, bootrec /scanos, and bootrec /rebuildbcd.
Each command serves a unique purpose. bootrec /fixmbr fixes the master boot record, bootrec /fixboot writes a new boot sector, bootrec /scanos scans for Windows installations, and bootrec /rebuildbcd rebuilds the boot configuration data.
Step 6: Restart Your Computer
Type exit to close Command Prompt and restart your computer.
Remove the installation media before restarting. Your computer should now boot up normally if the Boot Manager issue has been resolved.
After completing these steps, your computer should boot into Windows 10 without any problems. If issues persist, further troubleshooting may be needed.
