The Raspberry Pi costs just $40 and is cheap, versatile, and relatively powerful than its competitors. While most projects can be implemented using Raspbian, a fork of Debian Linux, this Raspberry PI OS is not the only option.
So many other operating systems can run on the Raspberry Pi. Just make sure you have a monitor, mouse, and keyboard handy before you boot it up, and a fast microSD card to run your operating system of choice.
Best Raspberry Pi Operating Systems
1. Linux operating systems based on ARM
Let’s clean up this Raspberry Pi OS collection first. It is estimated that there are over 80 Linux-based distributions for the Raspberry Pi. They range from Raspbian to Linutop and even Peebang.
While Raspbian is the default option (and recommended by the Raspberry Pi Foundation), you may prefer Ubuntu MATE or the lightweight DietPi OS. To get away from Debian-based distributions, there is a choice of Pidora (a Fedora-based distribution) and Arch Linux ARM.
Then there’s Kali Linux for testing the pen, and a range of operating system images designed for the Pi, covering many different purposes.
For youth Kano OS [Broken URL Removed] is an educational distribution available for all Pi computers, not just those sold by Kano.
Note that several operating systems (including Raspbian and Ubuntu MATE) are available with the NOOBS installer.
2. Raspberry Pi Media Centers

If you want to use your Raspberry Pi as a media center, you’ll have a good choice. While these operating systems are invariably built on Raspbian/Debian, they are also based on Kodi, the popular media center software. On these systems, you get a disk image to install just like any other Raspberry Pi operating system.
So what’s available? Well, OpenELEC versions are available for all Raspberry Pi consumer models.
Meanwhile, OSMC is compatible with Raspberry Pi 1, 2, 3 and Zero, with regular updates available through a dedicated admin screen. This is also available as an option in NOOBS.
Finally, LibreELEC is also available with the easiest installation thanks to the SD card creation tool for Raspberry Pi 2 and 3 users.
3. Pi OS RISK
Developed at Cambridge, RISC OS was the first operating system for ARM processors, developed in the 1980s. It saw widespread use in the Acorn Archimedes found in educational settings in the mid-1990s and was eventually replaced by Windows-based computers.
However, the RISC OS remains relevant and easy to set up.
For best results, you will need a mouse with a clickable scroll wheel, as the RISC OS user interface requires a mouse with three buttons. Once installed, you’ll find free apps in Packman and commercial options in the Store app.
You can install RISC OS using the NOOBS installation tool above, or download RISC OS for manual installation.
4. Plan 9

If you’re looking for an alternative to desktop operating systems, the UNIX-like Plan 9 might be the answer. It is an open source OS developed by the same team as the original UNIX.
The microSD card image can be burned in the usual way, and booting will bring you to the Plan 9 OS almost immediately.
In truth, the command line user interface can be difficult to understand. However, if you have experience with UNIX or want to try out such computing systems, Plan 9 is a good place to start. And if you need advice, check out this guide to Terminal Commands
5. Retro games for Raspberry Pi

Back to Linux, and a couple of operating systems for retro gaming can be installed on the Raspberry Pi. Powered by Raspbian/Debian, these tools allow you to run game ROMs and emulators and have user-friendly interfaces inspired by the user console that can be viewed with a game controller.
Several retro suites are available for you to choose from.
RetroPie offers emulation of a wide collection of retro platforms from the 80s, 90s and early 2000s. Its main competitor is RecalBox, which supports some later systems that RetroPie doesn’t have.
Prefer to stay away from them? Other options are available.
Lakka is considered «a lightweight Linux distribution that turns a small computer into a complete emulation console», while Pi Entertainment System (PES) is a suite of Arch Linux-based emulators.
