Comment 278 for bug 1289977

So, I'm getting tired of always unchecking Grub from automatic updates just to be sure that my system won't break again at the next reboot, and I would also like to upgrade to Ubuntu 14.10, which I have been delaying so far for the same reason (and then, 15.04 must be almost out). As a remainder: I was one of the people whose working dual boot system was screwed up when upgrading from 13.10 to 14.04 (because of a "misconfigured system" according to Phillip Susi, which I doubt, but if it is the case, it was misconfigured because of some bug in the first place)

So, is this what I need to do in order to prevent my computer from being bricked again by an upgrade?
> dpkg-reconfigure grub-pc
Will this ensure that updating grub and upgrading to 14.10 won't screw things up again?

And then I guess that will ask me for some parameters, or to choose something. If so, what command should I run to figure out what my current perfectly working configuration of grub is and make sure it is preserved, and/or to figure out the correct answer to whatever dpkg-reconfigure prompts may show up?
