Configure Grub Update to Install on Partition

Question

I have a Windows 7 & Ubuntu dual boot system. I just installed automatic updates to GRUB.

1. First update broke Ubuntu boot, which I fixed by installing grub to dev/sda3 in a chroot.
2. Second update installed itself to MBR (/dev/sda), which made Bitlocker ANGRY. Thankfully I had the recovery key still available.

Is there a way to configure grub automatic updates to install on a partition? In my case, the desired installation would be

grub-install --target=i386-pc --recheck --debug --force /dev/sda3

Answer 1

That configuration is stored in the debconf database on Debian based systems.

On Ubuntu 14.04 you can change it by running the following command:

sudo dpkg-reconfigure grub-pc
