The first thing you will need to do is download the Raspberry PI Imager onto your computer.
Open a web browser on your computer and go to raspberrypi.org/downloads/
Scroll down the page until you see the “Downloads” section and then click on the link for your operating system.
This guide assumes you are using Windows to create the SD-Card and therefore click on the “Raspberry PI Imager for Windows”.
After the file has downloaded navigate to the downloads folder and double click on the downloaded file. (IE Imager_1_4).
When the installer appears click on the “Install” button.
To run the Raspberry PI Imager, click “Finish” and as long as there is a tick in the “Run Raspberry PI Imager” option the program will load.
If the program doesn’t load, click on the start menu and search for “Imager” and the program should appear. Simply click on “Open”.
The process for installing the Raspberry PI operating system to the SD card is a simply 3 step process.
Click on “Choose OS”.
A list of potential operating systems for the Raspberry PI are shown in the list. For the purposes of this guide the “Raspberry PI OS (32-bit)” should be the option selected.
Raspberry PI OS is built specifically for the Raspberry PI and is the perfect starting point. The desktop environment used is lightweight, yet customisable, and there are a few key applications installed and the drivers for all the hardware components are installed.
The 32-bit operating system has more applications available for it than the 64-bit version currently and if you are using anything less than the 8-gigabyte version then there is little value to using a 64-bit operating system.
Make sure you have inserted the SD-Card into the slot on your computer. If your computer doesn’t have an SD-Card reader, you will need to obtain one.
Most external SD-Card readers connect to the computer via a USB port. If you are using an external SD-Card reader insert it into the USB port and then insert the SD-Card into the reader.
Click on the “Choose SD-Card” button and a list of SD cards will appear and there is usually only one. Make sure that the size resembles the size of the SD card you are using and click on it.
A message will appear asking whether you are sure you want to overwrite the contents of the SD-Card.
Note that this process will overwrite the entire contents of the SD-Card. If you are using an old card from your camera, make sure you have copied any photos from that card to another device first.
When you are ready click “Yes” to continue.
The process for installing the operating system to the SD-Card can take some time depending on the speed of your internet connection.
When the installation is complete you can remove the SD-Card from your computer and click “Continue”.
You are now ready to set up the Raspberry PI.
