Game won't play... help!

I recieved a burnout cicrle on my FIFA '09 game when my 360 was bumped while it was running. The disc no longer plays it just sits at a loading screen. Using a second copy, borrowed from a friend, a similar instance happened and the same mishap occured. This time, however, I loaded the game onto my hard drive first. When I put the first disc in, it still stalls at the loading screen, but the second disc works well enough to boot the game, which I can then run off my hard drive. My friend wants his game back tho, so I will have no way of starting the game. Is there any way I could create a boot disc or alter my system in any way to play FIFA. Any help is much appriciated! Thanks
