UEFI 64-BIT out of thin air

A Modern OS dev series for absolute beginners by Naitik Mundra.

I am Naitik Mundra, I am a full stack web developer. Pretty weird huh? A web dev guy teaches you OS. But this journey started in OCT 2025, when I decided to document my OS dev learning journey in a tutorial way, I will edit it from time as I learn more and more. And at end it will become a tutorial for absolute beginners, so they can grow a x86_64 UEFI 64 BIT Modern OS Out of Thin Air.

Unlike most operating system tutorials that stick to legacy BIOS and 32-bit environments, our OS targets modern hardware — it’s built for UEFI firmware and 64-bit processors from the ground up. I will still teach about legacy to clear your basics, but I will keep it concise yet informative enough. And it will be in fun and informal in tone, but just the tone not content.
