4.2.1 GNU/Hurd

Since GNU/Hurd is Multiboot-compliant, it is easy to boot it; there is nothing special about it. But do not forget that you have to specify a root partition to the kernel.

1. Set GRUB's root device to the same drive as GNU/Hurd's. Probably the command find /boot/gnumach or similar can help you (see find).
2. Load the kernel and the module, like this:

             grub> kernel /boot/gnumach root=hd0s1
             grub> module /boot/serverboot
        

3. Run the command boot (see boot).
