if you want to write an operating system from scratch this is the wiki almost everyone ends up using the OSDev community has been building it since 2004 it covers everything from the first bootloader instruction to writing filesystems memory managers and drivers the articles include real code you can compile and run yourself the Bare Bones tutorial gets you to a kernel that boots and prints to the screen in around 100 lines from there the wiki walks through every major piece of a real operating system
