Operating Systems (Raspberry Pi OS, Ubuntu, Other Distros)
One of the most powerful aspects of the Raspberry Pi is that it isn’t tied to a single operating system. Unlike a smartphone that locks you into iOS or Android, or a game console that only runs its own firmware, the Pi is an open platform. You can load a variety of Linux distributions — and even some non-Linux systems — depending on your project’s needs. This flexibility is why the Pi has become such a universal tool: it can be a desktop, a server, a media player, or an embedded controller, all by swapping SD cards or flashing a new image.
1. Raspberry Pi OS: The Official Standard
Formerly called Raspbian, Raspberry Pi OS is the official distribution supported by the Raspberry Pi Foundation. Built on Debian, it is optimized specifically for Pi hardware.
Key Features:
- Preloaded with educational tools like Thonny IDE for Python and Scratch.
- Lightweight desktop environment (PIXEL) that works smoothly even on older models.
- Full access to Debian repositories for software installation.
- GPIO libraries and tools baked in, so you can start coding hardware projects immediately.
- A 64-bit edition for Pi 4 and Pi 5, unlocking more memory and performance.
For most beginners, Raspberry Pi OS is the best starting point because it “just works.” Plug in an SD card with Pi Imager, boot up, and you’re ready to explore.
2. Ubuntu: A Familiar Powerhouse
For users who want a more mainstream Linux experience, Ubuntu has become the second most popular choice. Canonical maintains official builds of Ubuntu Server and Ubuntu Desktop for Raspberry Pi.
Advantages:
- Same environment as Ubuntu on desktops and servers — great for developers.
- Full Snap package support for easy software installation.
- Ideal for cloud integration with services like Ubuntu Core and Canonical’s IoT frameworks.
- More up-to-date software packages compared to Debian.
Use Cases:
- Developers who want consistency across their workstation, server, and Raspberry Pi.
- Enterprise IoT deployments where Ubuntu’s long-term support (LTS) is a benefit.
- Power users running Docker, Kubernetes, or AI frameworks.
3. Media-Focused Distributions
The Raspberry Pi shines as a home entertainment hub thanks to specialized media OS options:
- LibreELEC – A lightweight Linux distribution that runs Kodi media center. Turns your Pi into a full HTPC (Home Theater PC).
- OSMC – Another Kodi-based distro with a cleaner UI and active community support.
- Volumio / RuneAudio / MoOde – Focused on turning the Pi into a high-end audio player, often paired with DAC HATs.
These media OSes are plug-and-play: flash the card, boot up, and you have a streaming box rivaling Apple TV or Roku.
4. Retro Gaming Systems
Retro gaming has exploded on Raspberry Pi thanks to dedicated OS distributions:
- RetroPie – The most popular, supporting dozens of consoles from NES to PlayStation.
- Batocera – A polished alternative with automatic controller support.
- Lakka – Lightweight retro gaming OS built on RetroArch.
These are popular in classrooms and hobby setups because they combine nostalgia with programming challenges (e.g., configuring controllers, emulators, or custom menus).
5. IoT and Embedded Operating Systems
When the Pi is used as an IoT node, smaller OS options make more sense:
- Ubuntu Core – A minimal, containerized version of Ubuntu designed for security and IoT deployments.
- DietPi – Ultra-lightweight, optimized for minimal resource usage. Perfect for headless servers.
- HypriotOS – Docker-focused distribution designed for container deployments.
- BalenaOS – Tailored for IoT fleets, supporting remote device management and updates.
These OSes are great for when you’re deploying dozens or hundreds of Pis in a network and need security, scalability, and remote maintenance.
6. Security and Privacy-Centric Distros
Some enthusiasts run the Pi as a privacy hub or network security device:
- Pi-hole – Technically an application, but distributed as a ready-to-run OS image for network-wide ad blocking.
- Kali Linux – A security testing distribution with penetration tools. The Pi version makes a portable ethical hacking kit.
- Tails / Whonix (experimental ports) – For anonymity and privacy enthusiasts, though performance may be limited.
These options show how versatile the Pi is — one day it’s a media player, the next day it’s a cybersecurity toolkit.
7. Non-Linux Systems
Though Linux dominates, there are also alternative operating systems that demonstrate the Pi’s flexibility:
- Windows 10 IoT Core – Microsoft’s lightweight IoT platform, allowing developers to use C# and UWP apps.
- FreeBSD – A Unix-like OS with a reputation for stability and networking.
- Plan 9 / RISC OS – Niche but interesting for experimental or educational use.
These are less common but highlight the Pi as a truly open device.
8. Booting and Storage Options
The Pi traditionally boots from a microSD card, but newer boards (Pi 4 and Pi 5) support:
- Booting from USB drives for faster and more reliable storage.
- Network booting via PXE, useful in classroom clusters.
- Experimental support for booting from NVMe drives through PCIe adapters on Pi 5.
This flexibility means you can optimize the Pi for performance (SSD/NVMe) or cost (microSD).
Conclusion
Operating systems are the soul of the Raspberry Pi. With Raspberry Pi OS, you get the easiest entry point. With Ubuntu, you get enterprise-class features. With specialized distributions like RetroPie, LibreELEC, or DietPi, you can tailor the Pi to media, gaming, or IoT. The ability to swap between them — sometimes in minutes — is what makes Raspberry Pi such a powerful platform for both hobbyists and professionals.
