Connect your Pi to an ethernet cord or to your USB Wi-Fi adapter of choice. Plug your Raspberry Pi power supply into a wall to turn the Pi on.

The Pi 5 is significantly faster, and has potential AI uses, while the Pi 4 has more varied video out options and low power usage.

Once done, turn off the Raspberry Pi 4 and remove the card that has Raspberry Pi OS. Make sure that the USB drive containing flashed Windows 11 is connected and start the device.
