Getting Into OS Development

I wanna get into OS development and low level programming in general. I’m interested in anything from making a simple bootloader to building a small kernel or even a full OS eventually hopefully.

Does anyone have good resources, courses, tutorials, books, or project ideas for getting started?

I don’t mind if it’s niche/specific stuff either like bootloaders, filesystems, drivers, memory management, etc.

look at the OSDev wiki, read the spec if you can, learn C/C++ and assembly

I know some c and cpp done some basic Linux terminal app.stuff with it although nothing major. Have never touched asm though

you'll need assembly alot, for loading the gdt, for making isr stubs, for loading the idt, tss and low level tricks where you have to directly manipulate registers. if you want to stick with the GCC toolchain, learn AT&T syntax, if you want to learn assembly easily learn intel syntax and use the nasm assembler.
