Groovy install on non-efi hardware ends with grub install error

[Erick Brunzell]

Fairly simple install on non-efi Dell Latitude E6400. Just selected "something else" and used an existing partition for /. Another OS is already installed next to it (on sda3 I think).

Installation ended with a grub install warning. Not sure what will happen when I reboot but I was offered the opportunity to file this bug report so I did.

Bad on me - I didn't realize we now needed an EFI System partition on ALL installations.
