Your disc may be scratched, you can fix that by borrowing the game from a friend and install the game (from the game library tab) and then return it and it should work.
bring it to jb-hi-fi and they have a buffer wich will clean all the scratches off the disc.
Your disc must be faulty or scratched.
either your disc has been scratched or your 360 has problems. If other games work it means the 360 has scratched the disc when you put it in. Hope it helps and i suggest you try out a ps3 LOL.
if you still want to use it try and see if the disc still works. if it doesn't work buy one of those machines that clear scratches if you have money otherwise you will have to throw the disc away and buy a new one.
