Aha, so does that mean, that the bytes in the hidden sectors are always a 100 % copy of 
/boot/grub/core.img ?

So if I shrink the gap before 1st partition to a size, bigger than core.img, I'm save not having 
damaged GRUB 2 installation?

BTW: So I'm wondering if core.img on a USB-Pendrive-Ubuntu is little smaller to fit in the remaining 
31 sectors.
