how do you install games on your hard drive?

pretty simple question. i have a new 360 elite with a 120 gb hard drive and want to install forza 3 and halo 3 odst on the hard drive. does this make your games load faster? and do you still need the disc to play them?

If you want to install the game to the hardrive:

1. Insert the disk into the disc drive.
2. Under "My Xbox" select "Game Library."
3. Select the game you wish to install.
4. Select "Install to Hardrive."

And PRESTO, the game is installed.

great.. thanks alot. that's all i needed to know.

yeah i just finished installing both discs for forza 3. works great! thanks everyone for the help/
