Any idea what I am doing wrong? You need an EFI system partition and your boot loader (likely grub) installed there. You probably only have the boot loader installed for MBR boot, which will not be used for EFI boot. Depending on how much you've tweaked the installed system and what your experience with installing boot loaders is, it might be easier to just reinstall the system. Typically you should boot the install media with the boot method you're going to use. There's some background info for Ubuntu at [1], but I think with new machines the scales have tipped to UEFI working better than legacy boot. BR, Jani.
