[Bug 1573722] Re: Ubuntu 16.04 grub2 installation problem

[Phillip Susi]

Yes, you need to create an EFI system partition to install in EFI mode.
This is done automatically if you choose to format the drive and install
only Ubuntu, but if you are doing a side by side install, you need to
heed the warning that you should install in bios mode, and if doing a
manual install, you are on your own.
