Deleting Windows 11 can be a bit tricky, but with the right guidance, it’s totally doable. Whether you’re looking to downgrade or switch to a different OS, this guide will walk you through it. First, back up your files because they’re going to disappear when we’re done. Then, you’ll need a bootable USB or DVD with the operating system you want to switch to. Let’s get started!
How to Delete Windows 11
Deleting Windows 11 involves wiping your current operating system and replacing it with another. Below are the steps to help you accomplish this task safely and efficiently.
Step 1: Back Up Your Data
Before you begin, back up important files.
Backing up is crucial because once you delete Windows 11, all your files will be gone. Use an external hard drive or cloud storage to save everything you need to keep.
Step 2: Create a Bootable USB or DVD
Prepare a bootable device with your new OS.
This step requires downloading the installation files for your new operating system and using software like Rufus to create a bootable USB or DVD. Make sure the bootable device works before proceeding.
Step 3: Access BIOS/UEFI Settings
Restart your computer and enter BIOS/UEFI.
To boot from your USB or DVD, you’ll need to change the boot order. Restart your computer and press the required key (often F2, F12, or Del) to access these settings.
Step 4: Boot from USB or DVD
Select the option to boot from your prepared device.
Once in BIOS/UEFI, find the boot sequence settings and prioritize your USB or DVD. Save changes and restart. Your computer should start from the bootable device.
Step 5: Install the New Operating System
Follow the on-screen instructions to install your new OS.
Now, follow the prompts to install the operating system of your choice. This process will replace Windows 11 entirely.
After completing these steps, Windows 11 will be removed, and your new operating system will take its place. You’ll need to reinstall any applications you want to use and restore your files from the backup.
