Reinstalling Windows 11 from the BIOS might sound like a daunting task, but don’t worry—it’s easier than you might think. First, you’ll need to back up your important files. Then, access the BIOS menu on your computer, and change the boot order to prioritize a USB drive or DVD with the Windows 11 installation files. After that, follow the on-screen prompts to reinstall Windows 11. Once complete, you’ll have a fresh installation of Windows 11 ready to go!
Step-by-Step Tutorial on Reinstalling Windows 11 from BIOS
This guide will take you through the steps needed to reinstall Windows 11 directly from the BIOS of your computer.
Step 1: Back Up Your Files
Before you jump into the reinstall process, make sure you back up all your important files.
Backing up your data ensures that you don’t lose any pictures, documents, or software you might want to keep. Use an external hard drive or cloud storage to save these files securely.
Step 2: Create a Windows 11 Installation Media
You’ll need a USB drive or DVD with Windows 11 installation files to proceed.
Download the Windows 11 media creation tool from Microsoft’s official website. Then, use it to create a bootable USB drive or DVD. This will be your ticket to reinstalling the operating system.
Step 3: Enter the BIOS
Restart your computer and press the BIOS key (usually F2, F10, Delete, or Esc) during startup.
The BIOS is like your computer’s control room. Here, you can change settings that affect how your system runs. Look for instructions on the initial screen to determine which key to press.
Step 4: Change Boot Order
In the BIOS settings, set your USB or DVD as the first boot device.
This step is crucial because it tells your computer to load the installation files from the USB or DVD instead of the system hard drive. Navigate through the BIOS menu using the arrow keys to find the boot order settings.
Step 5: Install Windows 11
Save the changes in the BIOS, restart your computer, and follow the installation prompts.
After rebooting, your computer will start from the USB or DVD. You’ll see the Windows setup screen, where you can follow the instructions to reinstall Windows 11. Agree to the terms, select your installation type, and let the installation begin.
Once you have completed these steps, your computer will restart and load into a fresh installation of Windows 11. You’ll go through the initial setup process, which includes setting language preferences, creating a user account, and connecting to the internet. After that, you can restore your files from the backup you made earlier.
