when you install to the hard drive 5-7gb
No, however you can buy the game from xbox live marketplace and the game will be on your hard drive
Microsoft let you install the game to your hard drive to have better quality and more faster performance in the game therefore you still need the disc
If your 360 drive is flashed then yes you can once the copied game is the same as the game you installed but you could just play from the copied disc.
if you install the game onto your hard drive it will be whisper quiet
There are very little advantages to this but I belive that if you install a game to your hard drive your xbox will run a little cooler and if your disc shatters or breaks inside the xbox 360 itself then your data from your games is not lost and can be retrieved from your hard drive. Hope this helped.
Yes, but you won't be able to install the game or any DLC to your console.
you have to have the disc in the drive for it to play. When you install game to hard drive it makes it so the disc doesn't have to spin. Therefore it will not be scratched, overheated etc.
you should always be able to play online without installing a game
You cant.
Insert the disc into the xbox, then go to your game library>GTA IV>install to hard drive.
You can install Halo Reach to your hard drive like any other Xbox 360 game, however the game must be in the disk drive in order to play the game.(but if you have to put the disk its a waste of time to installing it)
