See bug #1770966 for someone complaining that they are no longer able to install Ubuntu because this question was removed ( and the automatic choice made to stick with an efi mode install instead of switching to bios mode ).

Also see the hundreds of apport reports that have been filed since 18.04 was released with people booting the installer in EFI mode with an existing bios mode install, and crashing because grub-efi can't be installed without an EFI system partition.
