Uninstalling Windows 11 from BIOS can be a bit complex, especially if you’re not familiar with the tech jargon. But don’t worry, I’m here to simplify it for you. Essentially, you’ll access the BIOS, change some settings, and then reinstall a previous version of Windows. This involves a few steps, but by following this guide, you can get through it without too much hassle.
How to Uninstall Windows 11 from BIOS
In this section, I’ll guide you through the steps to uninstall Windows 11 from the BIOS. We’ll go through accessing the BIOS, tweaking the settings, and rolling back to an earlier version of Windows.
Step 1: Access the BIOS
The first step is to restart your computer and enter the BIOS setup.
When your computer is starting up, you should see a message telling you which key to press to enter the BIOS. This is usually F2, F12, Delete, or Esc. Press the key repeatedly until you enter the BIOS.
Step 2: Change Boot Order
Step 2 involves changing the boot order to prioritize your installation media.
In the BIOS, navigate to the "Boot" tab using the arrow keys. Here, you’ll change the boot order to make your USB drive or DVD/CD drive the first boot device. Save the changes and exit the BIOS.
Step 3: Insert Installation Media
Step 3 requires you to insert your Windows installation media into your computer.
Once you’ve changed the boot order, insert your Windows installation media (either a USB flash drive or a DVD), and restart your computer. Your computer should now boot from the installation media.
Step 4: Start Windows Setup
Step 4 is to start the Windows setup process from your installation media.
When your computer boots from the installation media, you’ll see the Windows Setup screen. Follow the on-screen instructions to proceed.
Step 5: Choose Custom Installation
Step 5 involves choosing the "Custom" installation option.
In the Windows Setup menu, select the "Custom: Install Windows only (advanced)" option. This allows you to perform a clean installation of Windows.
Step 6: Delete Windows 11 Partition
Step 6 is to delete the Windows 11 partition.
In the "Where do you want to install Windows?" screen, you’ll see a list of partitions. Select the partition where Windows 11 is installed and click "Delete." Be careful, as this will erase all data on that partition.
Step 7: Install Previous Version of Windows
Step 7 is to install the version of Windows you want.
After deleting the Windows 11 partition, select the unallocated space and click "Next" to install your previous version of Windows. Follow the on-screen instructions to complete the installation.
Once you’ve finished these steps, your computer will restart with the older version of Windows installed.
