Reinstalling Windows 11 from the BIOS can fix a lot of issues and give your computer a clean start. Follow these steps to get the job done.

Step 1: Create a Bootable USB Drive

First, you’ll need to create a bootable USB drive with Windows 11 on it.

You can download the Windows 11 installation media from the official Microsoft website. Use a tool like Rufus to make the USB drive bootable. This step is crucial because it’s how you’ll install Windows 11.

Step 2: Insert the USB Drive into Your Computer

Next, plug the bootable USB drive into your computer.

Make sure your computer is off before you do this. Once plugged in, you’re ready to access the BIOS settings.

Step 3: Access BIOS Settings

Turn on your computer and immediately press the key to enter BIOS (this is often F2, F10, DEL, or ESC).

Check your computer’s manual if you’re unsure which key to press. You need to be quick because there’s a short window to press the key.

Step 4: Change Boot Order

In the BIOS menu, find the Boot Order settings and set your USB drive as the primary boot device.

This tells your computer to boot from the USB drive when it starts up. Save the changes and exit the BIOS menu.

Restart your computer to boot from the USB drive.

The computer will now boot from the USB drive, and the Windows 11 installation process should begin. Follow the on-screen prompts to reinstall Windows 11.

Step 6: Follow Installation Prompts

Complete the Windows 11 installation by following the on-screen instructions.

You’ll need to select your language, time, and keyboard preferences, and then click “Install Now.” Follow the prompts to complete the installation process.

Once you’ve completed these steps, Windows 11 will begin installing on your computer. The process can take some time, so be patient. Your computer will restart several times during the installation. After it’s done, you’ll have a fresh installation of Windows 11.
