Hi !!

I saw this tutorial http://wiki.osdev.org/64-bit_Higher_Hal ... ith_GRUB_2

but there have some runtime error code

error: unsupported tag: 0x8
error: you need to load the kernel first

this is the grub.cfg, as same as the tutorial

set timeout=1
set default=0

menuentry "myOS" {
multiboot2 /boot/kernel.sys
boot
}

Are you sure that your Multiboot 2 header is correct?

I completely mimic tutorial on

This does not answer my question.

Have you checked yourself that the Multiboot 2 header is correct?
