Build Your Own Operating System: A Hands-On Tutorial Series

This tutorial series takes you deep into the world of operating system development for x86 architecture. If you've ever wanted to really understand how computers work at the lowest level, this guide is for you. We'll break down the complex world of OS development into manageable, step-by-step modules. Throughout the series, I'll be using Hashx86, a working OS project, to show you real examples of how these concepts actually work in practice.

Why Build Your Own OS?

Creating an operating system from scratch is probably one of the toughest but most rewarding things you can do in computer science. Here's what you'll gain from this journey:

  • Real Understanding: You'll finally get how computers actually work - from the moment they power on to how they manage memory and run multiple programs at once.

  • Solid Programming Skills: You'll get really good at assembly language, C programming, and debugging tricky low-level problems. These skills will make you a much stronger programmer overall.

  • Satisfy Your Curiosity: Ever wondered what's really happening inside your phone, laptop, or server? Building your own OS will show you exactly how all those pieces fit together.

  • Stand Out from the Crowd: Let's be honest - not many people know how to build an operating system. This knowledge will definitely make you unique in academic circles, open source communities, and the job market.

What You'll Learn

I've organized these tutorials to take you through the key stages of OS development, using Hashx86 as our real-world example. We'll start from absolutely nothing and build up to a working kernel that can actually run user programs. Here's what we'll cover:

  • Setting Up Your Toolchain: Get your development environment ready to compile your custom OS.

  • Bootloader Essentials: Understand how your computer initiates with GRUB and hands control to your kernel.

Get Started Today!

Don't worry if you've never built an operating system before - this series assumes you know basic programming but starts from the ground up with OS concepts. I'll explain everything clearly, show you practical examples from Hashx86, and give you all the code you need to follow along.
