Binary package hint: grub2

I upgraded to the newest version of Ubuntu, 11.04. Once the upgrade is complete, the system gave me a grub error. He offered me the option to report the problem to developers and follow the steps here. I do not know what the problem is with grub, so does the solution to my problem?
