Uninstalling Windows 11 from BIOS might sound like a complicated task, but it’s doable if you follow the right steps. Essentially, you’ll need to access the BIOS, change the boot order, and then use a bootable USB or CD to reinstall another operating system. Here’s a guide to help you through the process in a step-by-step manner.
How to Uninstall Windows 11 from BIOS
If you’re looking to uninstall Windows 11 from BIOS, you’re essentially aiming to remove the operating system and replace it with another or go back to an earlier version. We’ll walk you through the steps to access your BIOS settings, change the boot order, and boot from a USB or CD to install a different OS.
Step 1: Access the BIOS
To start, you need to enter the BIOS setup on your computer.
Press the designated key (often F2, F10, Delete, or Esc) as soon as you power on your computer. It’s usually displayed briefly at the bottom of the screen when you first turn on your computer.
Step 2: Navigate to the Boot Menu
Once in the BIOS, locate the Boot menu.
The Boot menu is where you can change the order in which your computer looks for an operating system to start from. Use the arrow keys to navigate through the options.
Step 3: Change the Boot Order
Set the USB drive or CD/DVD drive as the first boot device.
This tells your computer to look for an OS on the USB or CD/DVD drive before the internal hard drive. Save your changes and exit the BIOS.
Step 4: Boot from the Installation Media
Insert your bootable USB or CD with the desired operating system and restart your computer.
Your computer should now start from the USB or CD, bringing up the installation screen for the new OS. Follow the on-screen instructions to proceed.
Step 5: Format the Hard Drive
During the installation process, choose to format the hard drive.
Formatting the drive will erase Windows 11 and all data on it. Make sure to back up important files before proceeding.
Step 6: Install the New Operating System
Follow the remaining steps to install the operating system of your choice.
After formatting the drive, the new OS will begin installing. This process can take some time, so be patient.
Once you’ve completed these steps, your computer will restart, and you’ll boot into the new operating system you installed.
