Getting ready

Since NOOBS creates a RECOVERY partition to keep the original installation images, an 8 GB SD card or larger is recommended. You will also need an SD card reader (experience has shown that some built-in card readers can cause issues, so an external USB type reader is recommended).

If you are using an SD card that you have used previously, you may need to reformat it to remove any previous partitions and data. NOOBS expects the SD card to consist of a single FAT32 partition.

If using Windows or macOS X, you can use the SD Association's formatter, as shown in the following screenshot (available at https://www.sdcard.org/downloads/formatter_4/):

Getting rid of any partitions on the SD card, using SD formatter

From the Option Setting dialog box, set FORMAT SIZE ADJUSTMENT. This will remove all the SD card partitions that were created previously.

If using Linux, you can use gparted to clear any previous partitions and reformat it as a FAT32 partition.

The full NOOBS package (typically just over 1 GB) contains Raspbian, the most popular Raspberry Pi operating system image built in. A lite version of NOOBS is also available that has no preloaded operating systems (although a smaller initial download of 20 MB and a network connection on Raspberry Pi are required to directly download the operating system you intend to use).

NOOBS is available at http://www.raspberrypi.org/downloads, with the documentation available at https://github.com/raspberrypi/noobs.
