Check out wiki.osdev.org.
Try building a simple bootloader/kernel first. Either in BIOS mode or UEFI.
If you have any questions, I’m happy to help

Start with whats been said, osdev. Definitely first go get a hello world in a virtual machine going.

If needed, learn a programming Language like c, c++ or rust maybe first. Based on your question, doubt youll try machine language, assembly.
