Hi everyone, in our previous lesson we learned what is Raspberry Pi and we got to know Raspberry Pi models. In this lesson, we will learn how to install Raspberry Pi OS (formerly Raspbian), which is the official operating system on Raspberry Pi, and different operating systems developed for Raspberry Pi. In this article, we will perform the installations with the Raspberry Pi 4 – 4GB model. You can also perform this setup on different Raspberry Pi models with the same methods.

Necessary materials:

  • Rasberry Pi 4 – 2GB
  • Raspberry Pi 4 Licensed
  • Power Adapter 5V 3A USB-C
  • Micro SD Card
  • Micro HDMI Cable


Raspberry Pi Imager Installation
In order to install the Raspberry Pi OS (Raspbian) operating system on the Micro SD Card, we need to install the Raspberry Pi Imager program, which is the official software of Raspberry Pi, on our computer. First, let’s download the Raspberry Pi Imager version that is compatible with your system from the Raspberry Pi website.

Raspberry Pi OS Operating System Installation

Raspberry Pi OS is a Debian-based operating system developed by Raspberry Pi. It is the most preferred operating system in Raspberry Pi models due to its interface and ease of use. In addition, it is an operating system that can be used for robotic coding training due to programs such as Scratch and Thonny IDE that come pre-installed in the operating system. Now that we know Raspberry Pi OS, we can continue the installation from where we left off.

Method #1 – Quick Download with Raspberry Pi Imager

We will start with the simplest method for installing Raspberry Pi OS and other operating systems. In this method, we will not need to download the Raspberry Pi OS (Raspbian) operating system to our computer, Raspberry Pi Imager will do this for us.

First, let’s insert the Micro SD Card into our computer. Then click the “Choose OS” button on the interface.

Since the steps after this stage are the same as the 2nd method, I explained the rest under the heading of “Method #1 and Method #2 Common Steps” after Method #2.

Method #2 – Manual Download via Browser

This method is a little more complicated than the first method, but you can install all operating systems with this method. If you like to try different operating systems like me, I recommend you to learn this installation method well.

There are 3 different operating systems available on the website. The features of these operating systems are as follows:

  • Raspberry Pi OS with desktop and recommended software: In this image, both an interface and some applications recommended by Raspberry Pi (such as LibreOffice) are available. That’s why it’s the largest image in size.
    Raspberry Pi OS with desktop: There is also a desktop in this image, but the download size is lower since there are no recommended applications.
    Raspberry Pi OS Lite: There is no desktop in this image, you do all your operations via terminal.

I will continue the installation by downloading the image of “Raspberry Pi OS with desktop and recommended software”.

Method #1 and Method #2 Common Steps

NOTE: This step and the next steps are common to both methods.

After selecting our Micro SD Card, the “Write” button will now be active. Click the “Write” button and wait for the Raspberry Pi OS (Raspbian) operating system to be downloaded and written to the Micro SD Card. Clicking the “Write” button will display a warning screen that all data on the Micro SD card will be deleted. Click the “Yes” button to continue the process.
