Instructions
Insert the USB flash drive into one of the USB ports on the Microsoft Xbox 360 console.
Turn on the console. The Xbox Dashboard menu will be displayed when the console starts.
Insert the game disc into the disc drive.
Scroll up to the "My Xbox" tab in the Dashboard menu. The default icon will be an image of the game inserted into the disc drive. This is the same icon normally used to start the game from the Dashboard.
Press the "Y" button. This will open the "Game Details" menu.
Select "Install Game" from the game details menu. A list of storage devices will appear.
Select the USB flash drive from the list of storage devices. The console will begin to burn the game to the flash drive. A progress bar will appear on the screen.
Wait for the progress bar to completely fill up. This indicates the game has been successfully burned to the flash drive.
