Reinstalling Windows 11 from BIOS can seem daunting, but it’s really about accessing the BIOS settings, configuring your boot sequence, and starting the installation process. You’ll need a USB drive with the Windows 11 installation files. Once in the BIOS, you’ll adjust settings to boot from this USB, follow a few on-screen prompts, and let Windows do its thing. By the end, you’ll have a fresh Windows 11 installation ready to go.
Step by Step Tutorial: Reinstall Windows 11 from BIOS
Reinstalling Windows 11 from BIOS ensures a clean start by wiping existing data and starting fresh. Here’s how you can do it in a few simple steps.
Step 1: Prepare a Bootable USB Drive
Create a bootable USB drive with the Windows 11 installation files.
To prepare your USB, download the Windows 11 media creation tool from the Microsoft website. Run the tool, and follow the prompts to create a bootable USB drive. You’ll need a drive with at least 8GB of space.
Step 2: Access the BIOS
Restart your computer and press the dedicated BIOS key during boot-up.
The BIOS key varies by manufacturer but is usually F2, F12, Delete, or Esc. Keep pressing it right after you power on your computer to enter the BIOS menu.
Step 3: Configure Boot Sequence
Change the boot order to prioritize the USB drive.
In the BIOS menu, locate the boot sequence settings. Set the USB drive as the first boot option. This lets your computer boot from the USB when starting up.
Step 4: Save and Exit BIOS
Save the changes and exit the BIOS menu.
Look for an option to save changes, often an F10 key, and confirm. Your computer will restart, using the new boot settings.
Step 5: Install Windows 11
Follow the on-screen instructions to install Windows 11.
Once the installation process begins, select your language, time, and keyboard preferences. Click “Install Now” and choose a clean installation if prompted.
After completing these steps, Windows 11 will begin installing on your computer. This process usually takes some time, during which your system might restart several times. Once finished, you’ll reach the setup screen to personalize your settings.
