How to do a clean install of Windows 11: Step-by-Step Guide

Installing Windows 11 with a clean slate means you’ll start from scratch, wiping your computer’s hard drive clean and installing a fresh copy of the operating system. This can help your computer run faster and get rid of any issues or unwanted files that have built up over time. Ready to get your PC running like new? Let’s dive into how to do a clean install of Windows 11.

Step by Step Tutorial for a Clean Install of Windows 11

Before we get into the nitty-gritty, understand that a clean install will erase everything on your hard drive. That means all your files, programs, and settings will be gone. It’s like giving your computer a fresh start. Make sure to back up any important data before proceeding.

Step 1: Create a Windows 11 Installation Media

You’ll need a USB drive with at least 8 GB of space to create installation media.

Creating a Windows 11 installation media is your first step towards a clean install. You can do this by downloading the Media Creation Tool from Microsoft’s official website and following the instructions to create a bootable USB drive.

Step 2: Boot from the Installation Media

Restart your computer and boot from the USB drive you just created.

To boot from the installation media, you’ll need to change your computer’s boot order. This is usually done by pressing a key (like F2, F12, Del, or Esc) as soon as the computer starts up to enter the BIOS or UEFI settings, then selecting the USB drive as the first boot option.

Step 3: Install Windows 11

Follow the on-screen instructions to install Windows 11.

During this process, you’ll need to select "Custom: Install Windows only (advanced)" to perform a clean install. This will allow you to delete any existing partitions and format your hard drive before the installation.

Step 4: Set Up Windows 11

Once the installation is complete, follow the prompts to set up Windows 11.

Setting up Windows 11 involves creating or signing in with a Microsoft account, setting your preferences, and choosing your settings. You can also decide whether to use Cortana, Microsoft’s virtual assistant.

After the clean install, your computer will be like brand new with a fresh copy of Windows 11. It should run smoother and be ready for you to reinstall your applications and restore your files from the backup you created earlier.
