Instructions
Turn on the Xbox 360 console. The Xbox Dashboard menu will appear.
Insert the original game disc. Insert “Disc 1” for multi-disc games, such as “Final Fantasy XIII.”
Scroll up to “My Xbox” in the Dashboard menu.
Press the “X” button to select the game. This will play the Xbox backup copy after the console verifies the original game disc is installed. The backup copy will not start if the game disc is not inserted.
