How To Reinstall Windows 11

Reinstalling Windows 11 can be a helpful solution when dealing with various issues such as performance problems or software errors. This guide will walk you through the process of reinstalling Windows 11 step by step.


Before starting the reinstallation process, ensure that you have:

  • A backup of your important files and data, as reinstalling Windows 11 will remove any personal files and installed applications.
  • A bootable USB drive with Windows 11 installation files or a Windows 11 installation DVD. If you don’t have one, you can create a bootable USB drive using the Media Creation Tool.

Step 1: Boot your PC from the installation media

  1. Insert the bootable USB drive or DVD with Windows 11 installation files into your PC.
  2. Restart your computer.
  3. During startup, press the designated key (usually F2, F10, F12, or DEL) to access the BIOS/UEFI settings. The exact key varies by manufacturer, so refer to your device’s documentation if necessary.
  4. In the BIOS/UEFI settings, navigate to the boot options menu and set the boot order to prioritize your installation media (USB drive or DVD).
  5. Save the changes and exit the BIOS/UEFI settings. Your computer will reboot and boot from the installation media.

Step 2: Start the Windows 11 installation process

  1. Once your PC boots from the installation media, you’ll see the Windows 11 setup screen. Select your language, time and currency format, and keyboard/input method, then click Next.
  2. Click on Install Now.
  3. Enter your Windows 11 product key if prompted, then click Next. If you don’t have a product key at hand, click on I don’t have a product key. You can activate Windows 11 later.
  4. Select the edition of Windows 11 you want to install, then click Next.
  5. Accept the license terms and click Next.

Step 3: Choose the installation type

  1. In the “Which type of installation do you want?” screen, select Custom: Install Windows only (advanced).
  2. Select the drive where you want to install Windows 11. If necessary, delete the existing partitions and create a new partition by clicking on New and then Apply.
  3. Click Next to start the installation process.

Step 4: Complete the installation

The installation process will take some time. Your computer may restart several times during this process. Once the installation is complete:

  1. Remove the installation media from your PC.
  2. Follow the on-screen instructions to set up your user account, preferences, and network settings.

Congratulations! You have successfully reinstalled Windows 11 on your PC. You can now restore your files and reinstall any necessary applications.
