    How to create an OS from scratch

    I started out with this tutorial: It doesn't get you too far but it explains the basics very well, so check it out. After that I looked up James Molloy's kernel tutorials (look it up on Google, it's all on a website). Be advised that he's got a bunch of errors and bugs in the tutorial, there is a whole page on it on the osdev wiki titled known bugs in the JamesM kernel all something like that, but it's still great and gets you pretty far. After that, I chose to develop a FAT32 driver on my own, I can link some sources or my own code for you as well, but it's really up to you to follow what you like. I also found a great youtube series (, check out his osdev series, he also has some cool stuff there. And as I said, good luck on your journey and you can ask me in a DM as well if you get stuck somewhere!
