I'm assuming that you're entering an Xbox 360 labeled disc, right? If so: Try taking the disc out and turning off your console. Turn it back on, then push the eject button to open the tray so you can insert the disc. Put the disc in and close the tray. Give
it a second.
It should now try to read the disc and if successful will show up under My Xbox, as the first selection. Just press the A button to play the game. Being a new Xbox 360, it shouldn't have problems playing games. If you have anymore problems, don't hesitate
to ask about them.
Did this solve your problem?
Sorry this didn't help.
