U cant fix a perfect circle

:-) sir i have had this happen many of times! no big deal if.. you find a friend with a copy the same game that you want to fix and play! should be easy if you not a loser! :-P then you pop your friend good copy of game into your xbox 360 and it will start up back out to the dashboard (or home) then go to games tab then to my games, and then you will see the cover of your game that your wanting to play! you click on it and then find the option to install to hard drive it should say "install" wait for it to copy the game to your hard drive! now once its done it will eject the disk! take it out and give it back to you're friend! now place you perfect circle disk into the game tray and close it! it should start right up man:D hope i helped!

Will the game play at all? Installing it will only work If the game will start, if it stays at the dashboard and says open tray, installing it will not work. There is no other way to fix it. Hope I could help.

just install someone elses game
