On the DVD
NOOBS (New Out Of the Box Software) provides an easy way to install operating systems on your Rasp Pi. The NOOBS installation manager offers the following operating systems:
Install from the DVD
l Raspbian "jessie" – Debian-based distribution recommended for beginning users.
Install from the Internet
l OpenELEC (RPi2 and RPi3) – Open Embedded Linux Entertainment Center is a Linux distribution that turns your Raspberry Pi into a Kodi media center.
l OSMC (RPi2 and RPi3) – Formerly called Raspbmc, OSMC is another Kodi media center distro.
l RISC OS – Not Linux, but a separate operating system that has been around since 1987 and traces its roots to some of the original developers of the ARM chip.
l Windows 10 IoT Core (RPi2 and RPi3) – Run Universal Windows Platform apps with this Pi-ready version of Windows.
The Raspbian image is located on the SD card and can be installed without access to a network. Other options require a network connection for network-based installation.
The DVD enclosed with this issue comes with a collection of some of the best and most popular Raspberry Pi distributions. To install a distribution from the NOOBS installation manager, format an SD card of at least 8MB with an SD card formatter (Windows and Mac)  and drag the files inside the uncompressed NOOBS folder to the SD card. For more information, and for instructions on how to prepare an SD card on Linux, check out the instructions on the Raspberry Pi website . Finally, unmount the SD card, insert it into the Raspberry Pi, and reboot.
In the NOOBS boot menu, select the operating systems you want to install. To try different systems later, hold down the Shift key at the Raspberry splash screen to bring back the NOOBS boot menu.
