Several types of OS, which can boot Raspberry Pi 2, are listed its official web site.
https://www.respberrypi.org/downloads/
The OS and installer that Raspberry Pi Foundation officially supports are:
- NOOBS
- Raspbian
Since NOOBS is considered as a set-up image (installer), Respbian is the only one OS, which is officially supported.
https://www.raspberrypi.org/downloads/raspbian/
Raspbian is derived from debian and optimized for Raspberry Pi.
Due to the difference in the license policy, Raspbian is NOT officially a part of debian.
As of today (October 2015), two different versions of Raspbian are distributed.
- Raspbian Wheezy (equivalent to Debian Wheezy (7.x)). It was released on May 5, 2015.
- Raspbian Jessie (equivalent to Debian Jessie (8.x)). It was released on September 24, 2015.
The operating system is distributed in dd image for microSD. The installation process is completed when this OS image is written into microSD, using dd tools.
To work on a Linux, please read the instruction that is listed at the URL below.
https://www.raspberrypi.org/documentation/installation/installing-images/linux.md
The required microSD card is at least 8GB and class 4. For more details, please read Quick Start Guide.

- To install Wheezy
- Download the image file on Linux.
- Unzip the downloaded image file.
- A microSD card, which the image will be written, is attached to Linux that you are working on via a card reader. Please check the device name, applying the command of df -h. For this example, the microSD card is recognized as /dev/sdf.
If you work on Ubuntu, and the microSD card is automatically mounted, please unmount the SD card.- Applying dd command, the image file is written into the SD card.
- When the writing process is completed, please remove the SD card from the SD card reader, for a while. Then, re-insert the SD card to the SD card reader. Please check whether the image file is correctly written into the SD card or not. If the image is successfully written into the SD card, the partitions such as shown below, are created inside the SD card.
If you work on Ubuntu, and the microSD card is automatically mounted, please unmount the SD card.
To boot Raspberry Pi from the SD card, just insert the SD card that the OS image is written to the SD card slot of Raspberry Pi 2, and please turn on its power.
