the last grub which you install (no matter if 2 or 1) into the MBR 
depends on the /boot/grub folder _from_ where you install.

=> re-install grub with all steps from your internal installation 
- while the external HD is connected also.
(update-grub, grub-install /dev/<bootdevice>)
Then you will be able to boot all found OS'es as far as they are 
connected.
