Here is my result of "debconf show grub-pc":

"dpkg-reconfigure grub-pc" has only "/dev/sda3" (my /boot partition) selected which probably explains why /dev/sda has not been updated by the Natty upgrade.

I would like to have grub only in /dev/sda3, but I don't like to have grub in /dev/sda. I would like only a basic boot sector in /dev/sda that would be system agnostic and only load the boot sector of the active partition (which, in that case would be /dev/sda3). That would allow me to easily drop a system partition and switch to an other system using only fdisk by activating an other partition.
