Step by Step Tutorial on How to Clean Install Windows 11

Before we dive into the nitty-gritty, it’s important to understand that a clean install will erase everything on your hard drive. So, make sure to back up all your important files. Ready? Great! Let’s walk through the clean install process.

Step 1: Create a Windows 11 Installation Media

To install Windows 11, you’ll need an installation media, which can be a DVD or a USB flash drive with a minimum of 8GB of space.

Creating a Windows 11 installation media is like making a key that unlocks the door to a fresh Windows environment. You’ll need to download the Media Creation Tool from Microsoft and follow the prompts. It’s pretty straightforward, just make sure to select the correct version of Windows 11 for your machine.

Step 2: Boot From the Installation Media

Plug in your installation media and restart your computer to boot from it.

Booting from the installation media is like starting your car with a new key. You’ll need to press a specific key (often F2, F12, ESC, or DEL) as the computer starts up to enter the boot menu. Select your USB or DVD drive from the list, and you’re on your way.

Step 3: Install Windows 11

Follow the instructions to install Windows 11. Be sure to select “Custom: Install Windows only” when prompted.

Think of this as the main event, where you lay down the new foundation for your computer. You’ll choose your language, time and currency format, and keyboard or input method. Then, when you get to the type of installation, make sure to pick the custom option. This will allow you to delete old partitions and make sure you’re starting fresh.

Step 4: Complete the Out-of-Box Experience

Set up your region, keyboard layout, network, and create a user account to finish the installation process.

After the installation, it’s like moving into a new home. You’ll need to tell Windows where you live (region), how you talk (keyboard layout), and how to get online (network). Then, create your user account – this is like putting your name on the mailbox.

After you’ve completed the installation, your computer will boot up with a brand-new installation of Windows 11. It’ll be clean, fast, and ready for you to start reinstalling your applications and restoring your files.
