Having trouble with Windows 11 showing a "Boot Device Not Found" error? Don’t fret! You can troubleshoot and fix this issue by checking BIOS settings, repairing the Master Boot Record (MBR), or even resetting your PC. This guide will walk you through each step in a clear and straightforward way to get your computer running smoothly again.
How to Fix Boot Device Not Found in Windows 11
This section will outline the steps to resolve the "Boot Device Not Found" error on Windows 11. These steps aim at ensuring that your computer correctly identifies the boot device and can load Windows properly.
Step 1: Check BIOS Settings
Ensure that the correct boot device is selected in the BIOS.
Enter your BIOS by pressing the BIOS key (usually F2, F12, Delete, or Esc) during startup. Navigate to the Boot tab and confirm that your hard drive or SSD is listed as the primary boot device. Save your changes and exit the BIOS. If your storage device isn’t listed, it might be physically disconnected or damaged.
Step 2: Reconnect Storage Devices
Reconnect your hard drive or SSD to ensure a proper connection.
Shut down your computer and unplug it from the power source. Open your computer case and check the connections to your hard drive or SSD. Make sure they are securely connected to both the motherboard and the power supply. Reassemble your computer, plug it back in, and try restarting your system.
Step 3: Repair the Master Boot Record (MBR)
Use Windows Recovery Environment to repair the MBR.
Insert a Windows 11 installation media (USB or DVD) and boot from it. Choose "Repair your computer" and navigate to Troubleshoot > Advanced options > Command Prompt. Type bootrec /fixmbr and press Enter. This command will attempt to fix any issues with the MBR. After running the command, restart your computer to see if the issue is resolved.
Step 4: Check for Faulty Hardware
Identify and replace any faulty hardware components.
If the problem persists, you might be dealing with faulty hardware. Use diagnostic tools to check the health of your hard drive or SSD. If these tools indicate a problem, consider replacing the faulty component. Sometimes, a problematic RAM module can also cause boot issues, so check and reseat your RAM sticks as well.
Step 5: Reset Your PC
Reset Windows 11 to resolve software issues.
If all else fails, you can reset your PC using the Windows Recovery Environment. Boot from the Windows installation media, go to Troubleshoot > Reset this PC, and choose to keep your files or remove everything based on your preference. This will reinstall Windows 11 and may resolve the boot issue if it’s software-related.
After completing these steps, your computer should boot up without displaying the "Boot Device Not Found" error.
