Backspace issue
You shouldn't discard the .data and .rodata sections. In case you were wondering, this is what's causing the strange limitations on string literals, and the reason why the tutorial author chose this insanity instead of a normal global const array.

Help with asm loops
But again at the moment my loop idea is not working, and apparently when edx reaches 2, it just doesn't goes further. The current bootloader code, without the changes above is here: https://github.com/dreamos82/Dreamos64/blob/master/src/asm/boot.s Is my idea so bad?

I need help with my OS
Another suggestion, that helped me a lot you can try to use qemu serial output to print some debugging (i'm using it a lot), it'se pretty easy to implement, you can have a look at how i did (https://github.com/dreamos82/Dreamos64/blob/master/src/kernel/debug/qemu.c)
