GTA 5 Xbox 360 Install Requirements
Does Grand Theft Auto V have any special install requirements?
Grand Theft Auto V is the largest and most ambitious game we have yet created, and takes full advantage of every ounce of processing power available in the current generation of consoles.
In order to provide the best possible experience for such a massive and detailed world, the game will have installation requirements on the Xbox 360 system.
For Xbox 360, Grand Theft Auto V will ship on two discs; Disc 1 will be used for a one-time mandatory install and Disc 2 will be used to play the game. After the install, players will be able to enjoy both Grand Theft Auto V and Grand Theft Auto Online without any need to switch discs.
This initial install will require an Xbox 360 Hard Drive or an external 16GB USB flash drive with at least 8 GB of free space. If using a USB flash drive it must be at least USB 2.0 with a minimum 15mb/s read speed and formatted for Xbox 360 use. A new USB flash drive is recommended to ensure optimum performance.
I have the Xbox 360 4GB or Xbox 360 Arcade/Core system so I don’t have 8GB free. Can I play Grand Theft Auto V on Xbox 360 by installing to a hard drive or USB flash drive?
You can install Grand Theft Auto V to an Xbox 360 hard drive or USB flash drive (sold separately) on Xbox 360.

I know Grand Theft Auto V has an 8 GB mandatory install. If I want to install the Play Disc too, through Xbox Home (dashboard), is that possible?
For optimal performance, we recommend only installing the Install Disc, and not also installing the Play Disc to the Xbox 360 Hard Drive or USB drive via Xbox Home (dashboard). You will be prompted to install the Install Disc the first time you boot the game.
