How to Fix UEFI Boot Windows 11: Step-by-Step Troubleshooting Guide

How to Fix UEFI Boot Windows 11

Fixing a UEFI boot issue in Windows 11 might sound complicated, but it’s actually a straightforward process. You’ll need to access the UEFI firmware settings, repair the boot files, and make sure your system is set to boot from the correct drive. In just a few steps, you’ll be back up and running.

Step-by-Step Tutorial to Fix UEFI Boot Windows 11

We’re going to go through the exact steps needed to fix the UEFI boot problems in Windows 11. By the end of this process, your computer should boot up normally without any issues.

Step 1: Access the UEFI Firmware Settings

To start, you need to access the UEFI firmware settings.

You can usually do this by pressing a specific key (like F2, F10, or Del) right after turning on your computer. Once you’re in the UEFI settings, you’ll see a lot of options, but don’t worry—we’ll only be touching what we need to.

Step 2: Check Boot Order

Once in the UEFI settings, make sure the boot order is correct.

The boot order determines which drive the system tries to boot from first. Ensure your primary hard drive is at the top of this list. Use the arrow keys to make changes.

Step 3: Repair Boot Files

Next, you’ll need to repair the boot files using the Windows Recovery Environment.

Restart your computer while holding the Shift key to enter the recovery mode. Navigate to Troubleshoot > Advanced Options > Command Prompt. Type "bootrec /fixmbr" and press Enter. This command will repair the Master Boot Record.

Step 4: Rebuild Boot Configuration Data (BCD)

After fixing the MBR, you’ll want to rebuild the Boot Configuration Data.

In the same Command Prompt window, type "bootrec /rebuildbcd" and press Enter. This command will scan for Windows installations and add them to the BCD.

Step 5: Restart Your Computer

Finally, restart your computer to see if the UEFI boot issue is resolved.

Simply close the Command Prompt and choose the “Continue” option to boot into Windows 11. If everything went well, your system should start up normally.

After completing these steps, your computer should boot up without any issues. If the problem persists, you might need to repeat the process or consult a professional.
