Uninstalling Windows 10 completely might sound like a complicated task, but it’s actually pretty straightforward if you follow a few simple steps. Here’s a quick summary: back up your files, create a bootable USB with a new operating system, boot from the USB, partition your hard drive, and then install the new OS, effectively removing Windows 10 in the process. Ready to dive in? Let’s break it down step-by-step.
How to Uninstall Windows 10 Completely
In this section, we’ll walk through the exact steps you need to uninstall Windows 10 completely and install a new operating system. This process will erase your current Windows 10 installation.
Step 1: Back Up Your Important Files
Make sure you back up any important files before starting the process.
Losing your data is never fun. Use an external hard drive or cloud storage service to save files like documents, photos, and videos. This way, you won’t lose anything important when we wipe Windows 10.
Step 2: Create a Bootable USB with a New OS
Make a bootable USB drive with the operating system you want to install.
You’ll need another computer for this step. Download the installation files for your new OS (like Linux or another version of Windows), and use a tool like Rufus to create a bootable USB drive. This USB will be your ticket to a new operating system.
Step 3: Boot From the USB
Insert the bootable USB drive into your computer and restart it.
You may need to change the boot order in your BIOS settings to make your computer boot from the USB. Usually, you can enter the BIOS by pressing a key like F2 or DEL when your computer starts up. Look for a menu that lets you change the boot order.
Step 4: Partition Your Hard Drive
Use the OS installer to partition your hard drive.
When you boot from the USB, you’ll get into the installation menu of your new operating system. Here, you’ll be able to delete the old Windows 10 partitions and create new ones. This step essentially wipes out Windows 10 from your hard drive.
Step 5: Install the New Operating System
Follow the on-screen instructions to install the new OS.
The installation process will vary depending on what new OS you’re installing, but the steps are usually pretty straightforward. Follow the prompts, and you’ll have a fresh OS installed in no time!
Once you’ve completed these steps, your computer will boot into the new operating system, and Windows 10 will be completely removed.
