Comment 8 for bug 1303790

It is related only tangentially: ubiquity defaults to /dev/sda, which generally is the right thing to do for bios based systems, but grub-efi is installed to the right place anyhow. The problem is that ubiquity then does its own additional diddling with the disk it thinks grub was installed to, and attributes the failure of this diddling to grub-install. I believe that additional diddling only makes sense for a bios install so should probably be made contingent upon that, but even when it is done and fails, it should not claim that grub-install failed when it didn't.
