Bug Description

I dual boot Xenial and OSX on a MacBook Air. I use rEFInd as my boot loader to manage them. However, every time there's a grub update, grub just silently overwrites my bootloader, which makes it so that I am unable to boot into OSX.

Grub updates should NOT overwrite the default bootloader, period. At the very least, it should halt installation and prompt the user with something like:

It looks like grub is not your current bootloader. Do you wish to replace your existing bootloader?

I installed rEFInd BEFORE I did the ubuntu install on this machine, so it predates even the Xenial installer. Thus I should not have to re-install rEFInd after every grub update.
