Install Windows 11

  • Once you have gotten the leaked Windows 11 build, it is time to flash the ISO image on a thumb drive. Make sure you have at least 16 GB of storage space on a USB flash drive before you begin the process. Now is the time to go get Rufus (Free).
  • Then, launch Rufus and select the Windows 11 ISO image by selecting it from the SELECT drop-down menu. Make certain that the USB thumb drive is selected from the “Device” drop-down menu. Keep everything as it is and press the “START” button to begin.


  • Follow the very first set of on-screen instructions to allow Rufus to flash Windows 11 onto the USB drive at this point.
  • As soon as the process is completed, connect the USB drive to the computer on which Windows 11 will be installed. If you plan to install Windows 11 on the same computer, leave the Flash drive plugged in. After that, you’ll need to restart your computer.
  • Next, while your computer is booting up, keep pressing the boot key constantly. You have the option of selecting the boot device. The Esc and F9 keys are functional on the majority of computers. You may be able to find the boot key for your laptop by searching on the internet. The following are the keys that are used to boot a device: F9, Esc, F12, F10, and so on.
  • Select the USB thumb drive from the boot device options that you just created on the leaked Windows 11 by selecting it from the boot device menu.
  • After then, the Windows 11 installation process will begin. If you receive a popup asking whether you want to continue with the update or perform a clean installation of Windows 11, take the easier option. If you want to clean up a fresh installation of Windows 11, select the option “No.”


  • The installation procedure is now the same as it was for Windows 10. Simply select Install Now -> I don’t have a product key ->  Select Windows 11 Pro or any other edition from the drop-down menu.


  • To install Windows 11, select the partition on which you want the operating system to be installed. Following that, Windows 11 will begin to be installed on your computer.


  • Soon afterward, your computer will reboot, and a new setup page for Windows 11 OOBE will be presented on the screen. The boot disk can now be removed from the computer. Pay attention to the instructions displayed on the screen and connect with your Microsoft account. You may also choose to create an account that is not connected to the internet or commonly known as an offline account.


  • Finally, you have completed the installation of Windows 11 on your computer.
