Comment 282 for bug 1289977

I've encountered the same problem. Is this an issue that won't be fixed?
I thought I had a pretty normal setup. Dual boot windows 7 and Ubuntu. Installed Windows first, then Ubuntu, used all default/recommended settings. Now left with a totally trashed bootloader for both OSes, and wasted best part of a day trying to fix it. Now resorting to reinstalling both OS. In future, a bright red warning, something along the lines of "Updating Grub may render your computer unbootable" would be handy, so its clear that unticking the Grub package upgrade might be a good idea.

Since I'm now reinstalling my entire system, what is a "normal" setup? Ie what setup will survive future Grub updates? Baring in mind I'm dual booting with windows, both on same HD.
