Re: Next release grub
You could run the boot info script in darkod's signature or make yourself a boot-repair disk or even install boot-repair in your working installation. These options will allow you to pass very good configuration detail to us for review. We'll be able to see if there is something to be addressed.
No offense, just a reminder. When something happens, the first thing to think of is what did I just do or do since the last boot in this case. It is right that fixing boot issues very rarely causes a need to re-install anything more than grub.
