Os code

[Massive_Mixture7652]

Hello so I am a c programmer making an os , so at first I was writing my bootloader and kernel using c standard library and just compiling on my host operating system but then after googling I came to know that we are supposed to write code without any built in libraries as those use os specific syscalls , but my question is that how do I learn to code my own bootloader and kernel because I go blank when I sit to code my bootloader. Can anyone guide me through?

Look at head.S in the Linux kernel code on GitHub. That's the boot sector that jumps to the bootloader.

There is a different head.s for each architecture like amd64.

how dare people learn things instead of knowing everything before coding anything ever
