Introduction

This tutorial is designed to give you a basic understanding of SD Cards and how to write different images to the SD card of your choice.

SD cards, short for Secure Digital, are everywhere you look now, from digital cameras, to phones and tablets, and even Single Board Computers (SBCs). In many cases your SBC won’t come with Linux or any other operating system on it. It is up to you to provide the OS on an SD card. With the exception of Noobs for Raspberry Pi, this is usually not a drag and drop procedure.

In this tutorial, we are going to talk about different types of SD cards and readers, formatting your card to erase any data that may be lurking around, installing your image, and then how to use any left over space on the card.

Single Board Computers, such as the Raspberry Pi, use SD and microSD cards to house various operating systems. Pictured here: a microSD card with full-size adapter.

Required Materials

To follow along with this tutorial, you will need an SD card, and a card reader (see related sections for more information on different types). You will also need a computer and an Internet connection (if you don’t have all the software and your image already on your computer). Last, you’ll want your SBC or whatever device into which you are installing your card.
