create a grub.cfg and leaves me screwed.

So you can ask what's grub-install for? It doesn't install grub.

"grub-install /dev/sda" creates a grub.cfg
"grub-install --root-directory=xxxxx../dev/sda" does not.
Both installs grub.

"grub-mkconfig" prints out output, does nothing else.
"grub-mkconfig -o /boot/grub/grub.cfg" creates grub.cfg
But use "update-grub" instead of "grub-mkconfig"
