Bug Description
During the ubuntu 16.04 upgrade, the installation failed and the software threw an exception:
Grub failed to install. System would not be able to boot the new ubuntu.
However, I have been running Ubuntu 14.0n on the same hardware. I was not clear to me
why the Grub software failed to install. What will be my resolution next?

Your disk is currently partitioned to boot in bios mode, but you booted the 16.04 installer in EFI mode. A warning message prompted you that this could be a problem and recommended performing a bios mode install instead, but you chose not to. You either need to perform the bios mode install, or partition the disk using GPT and set up an EFI system partition to install in EFI mode. This will be done for you if you choose the "use entire disk" guided install option.
