Raspberry Pi Imager

Raspberry Pi Imager is the official software by the Raspberry Pi Foundation aimed to simplify recording operating system images compatible with the popular micro-computer onto your home unit. Specifically, it streamlines writing and saving OS software on external SD cards. That way, they're easier to use later on -- you can pop it right in and burn it onto your Raspberry Pi unit without the extra runaround of using external tools.

The list of officially recognized and supported operating systems that you can download and install from Raspberry Pi Imager includes well-known titles like Raspbian, LibreELEC and Ubuntu. Plus, each comes with different versions and flavors for each Raspberry Pi edition. For example, LibreELEC has versions for Pi Zero/1, Pi 2/3, and Pi 4. Ubuntu comes with the latest updates like LTS (as its standard).

Once you've selected the operating system you're looking for, all you need to do is pop in your SD -- or MicroSD with an adapter -- to a card reader for your Raspberry Pi unit, and proceed to run your selected ISO. This is going to take a couple of minutes and you're going to need to have your disk image on hand to stick it into your Raspi.
