How Can I Play 360 Games from the Hdd Without Having the Disk in the Tray?

For example, I want to rent a game from blockbuster and I copy it to my xBox 360 Hard Drive (HDD), how ccan I still play the game without having the disk?, which will happen after I leave it at blockbuster again

Suggestion:

you cant , unless you mod your xbox, which is illegal. asking how to do something illegal on yahoo answers is, well, illegal.

technically you already broke the law by asking this question.
