HOW TO INSTALL "LINUX UBUNTU OS" ON A RASPBERRY PI


This is SIMPLE!
Install Raspberry Pi OS using the Imager for Windows (or whatever you have)
Then choose OS... Ubuntu (for 2/3/4 or whatever pi you have)
Now choose your drive that you stuck the MicroSD into. (oh yeah, you need a microSD card. it doesn't have to be very large in file size)
Now click WRITE

That's it!

Use your keyboard and mouse if you got it. or just a keyboard!
