Installing operating system images

This resource explains how to install a Raspberry Pi operating system image on an SD card. You will need another computer with an SD card reader to install the image.

Before you start, don’t forget to check the SD card requirements.

Using Raspberry Pi Imager

Raspberry Pi have developed a graphical SD card writing tool that works on Mac OS, Ubuntu 18.04 and Windows, and is the easiest option for most users as it will download the image and install it automatically to the SD card.

• Download the latest version of Raspberry Pi Imager and install it.
  • If you want to use Raspberry Pi Imager on the Raspberry Pi itself, you can install it from a terminal using sudo apt install rpi-imager.
• Connect an SD card reader with the SD card inside.
• Open Raspberry Pi Imager and choose the required OS from the list presented.
• Choose the SD card you wish to write your image to.
• Review your selections and click ‘WRITE’ to begin writing data to the SD card.

Note : if using the Raspberry Pi Imager on Windows 10 with Controlled Folder Access enabled, you will need to explicitly allow the Raspberry Pi Imager permission to write the SD card. If this is not done, Raspberry Pi Imager will fail with a “failed to write” error.

Using other tools

Most other tools require you to download the image first, then use the tool to write it to your SD card.

Download the image

Official images for recommended operating systems are available to download from the Raspberry Pi website downloads page.

Alternative distributions are available from third-party vendors.

You may need to unzip .zip downloads to get the image file (.img) to write to your SD card.

Note : the Raspberry Pi OS with desktop image contained in the ZIP archive is over 4GB in size and uses the ZIP64 format. To uncompress the archive, a unzip tool that supports ZIP64 is required. The following zip tools support ZIP64:

• 7-Zip (Windows)
• The Unarchiver (Mac)
• Unzip (Linux)

Writing the image

How you write the image to the SD card will depend on the operating system you are using.

• Linux
• Mac OS
• Windows
• Chrome OS

Boot your new OS

You can now insert the SD card into the Raspberry Pi and power it up.

For the official Raspberry Pi OS, if you need to manually log in, the default user name is pi, with password raspberry. Remember the default keyboard layout is set to UK.
