Things You'll Need
Instructions
Power on your console and log in to Xbox Live. A dialogue window will appear if your console needs to be updated. Select "Yes, update" if applicable. You must have the NXE update or newer to save a game to the hard drive.
Turn off the console.
Connect a HDD to the console if necessary by snapping it into place in the HDD bay. Push the larger side of the HDD down first then push the smaller side until it clicks in.
Turn on the console and insert your desired game disc into the tray and close it.
Exit to the dashboard and go to the "My Xbox" section. Scroll to the first blade of this section, which should show the game that is currently in the disc drive.
Press "Y" to pull up the "Game Details."
Choose "Install to Hard Drive" and wait for the process to complete. A progress bar displays on screen.
Press the "A" button when the saving process completes.
