         The answer is :-)

     You can not use the Master Boot Record because Ubuntu can not 
handle gpt language :-(

     You can however use ANY other partition as the source for Grub2. I 
am not sure how the Grub2 does  this but you need to watch the system 
load and have the the address you want to use written down. It will be 
similar to /dev/sda3 :-P
