Doing a clean install of Windows 11 involves wiping your computer’s hard drive and installing a fresh copy of the operating system. This can help solve many issues like slow performance or software glitches. Before you begin, make sure to backup your important files since the process will erase everything on your hard drive.
How to Clean Install Windows 11
Here’s a detailed guide to walk you through the clean installation process of Windows 11.
Step 1: Backup Your Data
Before you do anything else, make sure to backup all your important files.
You can use an external hard drive or cloud storage services like OneDrive or Google Drive to save your documents, photos, and videos. This step is crucial because a clean install will erase everything on your hard disk.
Step 2: Create a Windows 11 Installation Media
Download the Windows 11 Installation Media Creation Tool from Microsoft’s website and create a bootable USB drive.
You’ll need a USB drive with at least 8GB of space. Follow the on-screen instructions to download the Windows 11 ISO file and copy it to your USB drive. This will be your installation media.
Step 3: Boot From the USB Drive
Insert the USB drive into your computer and restart it. Press the appropriate key to enter the boot menu (usually F12, Esc, or Del).
Choose the USB drive from the boot menu to start the installation process. If you’re not sure which key to press, check your computer’s manual or manufacturer’s website.
Step 4: Start the Installation Process
Select your language, time, and keyboard preferences, then click “Next.” Click “Install now” to begin the installation.
This step will take you to the Windows Setup screen, where you’ll be asked to enter your product key. If you don’t have it, you can skip this step and enter it later.
Step 5: Choose Custom Installation
When prompted, select “Custom: Install Windows only (advanced).” This option allows you to perform a clean installation.
This step will show you a list of partitions. Delete all the existing partitions to create unallocated space. Click “Next” to install Windows 11 on your empty hard drive.
Step 6: Complete the Installation
Follow the on-screen instructions to finish the installation process. Your computer may restart several times.
Once the installation is complete, you’ll need to set up your Windows 11 user account and preferences. Follow the prompts to customize your settings.
Step 7: Reinstall Your Programs and Restore Data
After Windows 11 is installed, reinstall your programs and restore your backed-up files.
Go to the previously saved backup to retrieve your documents, photos, and other important files. Install your favorite applications to get back to your normal workflow.
After you complete these steps, your computer will be running a fresh version of Windows 11. You’ll notice improved performance and fewer errors.
