"To install Windows 11 Pro 22H2 build 22621 on a device with UEFI firmware, you'll need to create a bootable USB drive with the installation media. You can use tools like Rufus or the Media Creation Tool to create a UEFI-compatible bootable USB.
Once you have your bootable USB, make sure your device is set to boot from UEFI. You can do this by entering the BIOS settings (usually by pressing F2, F12, or Del) and changing the boot order to prioritize UEFI booting.
With your UEFI bootable USB ready, you can now proceed with the installation. Insert the USB drive, restart your device, and enter the BIOS settings. Set the USB drive as the first boot device, save the changes, and exit the BIOS settings.
Your device should now boot from the USB drive, and you'll be greeted with the Windows 11 installation wizard. Follow the prompts to select your language, region, and other preferences, and then click 'Install Now' to begin the installation process.
During the installation, you'll be prompted to select the edition of Windows 11 you want to install. Choose 'Windows 11 Pro' and enter your product key when prompted.
Once the installation is complete, you'll be taken to the Windows 11 desktop. You can then install drivers, updates, and applications as needed.
