Could someone guide me on what path/steps to take to create a simple bootable hello world program? I have the basic knowledge of C/C++.
My aim is to create a very simple OS.
I would like as much relevant links to references and samples as possible.
See this. It's a tutorial for a very basic boot loader. It doesn't have much to do with C/C++, but it has some really good information on the basic building blocks of a bootloader.
If you're really curious about the building blocks, there are more in-depth resources in the form of textbooks. This tutorial, for instance, doesn't explain why the boot loader must end with 55 AA. In addition, it's relatively narrow.
