You can easily install Raspberry Pi OS using the Raspberry Pi Imager. This is an official imaging application that makes the microSD card flashing process much easier and more welcoming to new users. You can find a thorough overview of how to use the Raspberry Pi Imager here.
- Download the Raspberry Pi Imager installer for your Operating System from the Raspberry Pi downloads page.
- Run the installer and complete the setup by following the prompts.
- Launch Raspberry Pi Imager and click Choose OS.
- Select Raspberry Pi OS from the list.
- Click Choose SD card and choose the microSD card you want to flash the new OS to and click Write.
When the imager is finished, you can connect your microSD card to the Pi and boot it up.

There are several options when it comes to imaging software, a popular application known to work well with Raspberry Pi images is Etcher. This program can be used to flash any compatible image to the microSD card for your Pi.
- Download and install the imaging application of your choice.
- Download the Raspberry Pi OS image from the Raspberry Pi downloads page.

There are a few issues you're likely to run into while trying to set up the new Raspberry Pi OS.
OS Not Loading
If the Raspberry Pi OS image isn't booting, format the SD card and try to image it again. If it still won't boot properly, make sure the SD card is large enough. You may want to revert to Raspbian Buster to determine if the issue is with the OS or the Pi hardware.
You may find that some software is completely incompatible with the new OS. You can wait for the developers to update the program to work with the new changes or revert to an older edition like Raspbian Buster.
If you receive an error when trying to image the microSD card, research the error verbatim online to determine exactly what the problem is. If you can't find anything specific to your issue, make sure the microSD card is big enough to support Raspberry Pi OS. You may need to try formatting the card before trying to reimage it.
The Raspberry Pi Pico and Raspberries Pi Zero are miles apart when it comes to specs, form factor, and software support.
