You can play a game directly from the game disc without installing it to your hard drive. But you can also install it to improve load times and minimize game disc access. Installation Process: First, you need to insert the game disc into your disc drive. The game will start as the default option is to automatically start the game. If the game starts, you’ll have to exit the game, and get back to the Xbox Dashboard. You need to go to Home and highlight the game you want to install with your controller. Press X on your controller and select Install to Hard Drive. You’ll see a progress indicator while your game is being installed to your hard drive. The installation might take up to 12 minutes. Notes: Your hard drive must have sufficient free disc space as installing a game requires between 4 and 8 gigabytes of free disc space. You also need to have the game disc to start the game once you have installed it on your hard drive. But the benefits are that installing games on your hard drive minimizes game disc access and reduces load times. You are not allowed to install Original Xbox games on your Xbox 360 hard drive.
