Can I install an xbox 360 game to the hard drive without the disc?

Hello. I own some games that are scratched and some sections of the game work but most of them do not. I want to install the games to my hard drive and play them, because the discs are readable, but the discs are too scratched to install the whole game. Is there a way for me to install the game through an outside source, like my computer or a flash drive, so that I can play the games with my discs?|||No, you need the disc... I'd suggest borrowing a copy from a friend long enough to install it, or renting a copy from Blockbuster or Gamefly to install it.|||No. In order for you to download the game to your hardrive, you need a clean game with no scratches then you can run it without a disc or a scratched one. I remember when my mw2 got scrathed i borrowed my next door neighbors and downloaded it and then i got to play it with my scratched disk.|||No You Need The Disc To Install It But After You Install It You Don't Need The Disk To Play?
