Bug Description
When installing in EFI mode to a disk that is partitioned without an EFI system partition, you do get a warning message that this may cause a problem and suggests that you go back and do a bios mode install instead. The way that it is worded, and the fact that the button to switch to a BIOS mode install is labeled "cancel", is very confusing and has lead to hundreds, if not thousands of users clicking the OK button instead, and proceeding with an install that is doomed to fail. This message really needs to be clarified.
Instead of clarifying, the question was removed, and grub-efi is always used, which crashes the install. grub-pc is the correct version to use in this case. This is a release regression that needs corrected for 18.04.1.

Your disk is currently partitioned to boot in bios mode, but you booted the installer in EFI mode. A warning message prompted you that this could be a problem and recommended performing a bios mode install instead, but you chose not to. You either need to perform the bios mode install, or partition the disk using GPT and set up an EFI system partition to install in EFI mode. This will be done for you if you choose the "use entire disk" guided install option.
