You'll want your Xbox's disc tray to be empty before proceeding. Do so using the adapter cable from before. You'll find this option at the top of the Xbox's main menu. It's in one of the controller slots (e.g., Controller 1) in one of the corners of the screen. You'll find this option near the bottom of the screen. Doing so will bring up a list of locations to which you can copy your file. Press A when prompted to do so. It should be labelled SID 5.11 Installer USB. This will paste the installer onto your Xbox's hard drive. Once the installer is finished pasting, you can proceed with finally modding your Xbox.
