Note that "root=(something,else); multiboot
(hd0,5)/boot/grub/core.img" is *not* functionally equivalent to
"root=(hd0,5); multiboot (hd0,5)/boot/grub/core.img". The multiboot
loader actually uses the value of $root and passes that information
along to the kernel its loading, in the case of loading grub it's used
to find the correct device value for $prefix.

Try actually using "search --set=root --fs-uuid=UUID_HERE; multiboot
/boot/grub/core.img".
