If I have existing data on disk built by a previous version of Ubuntu (in BIOS (legacy) mode, or a previous Windows install, and no EFI system partition on disk; the installer presents three choices:

- Replace $existing and reinstall. (if a previous Ubuntu install was found)
- Resize and install
- Erase disk and install.

The first two options will attempt to complete the installation in EFI mode (as they should) but do not create an EFI system partition, which is required as a place to put shim and grub on disk for booting. The installer will then crash / fail as grub-install fails to find the ESP when copying the bootloader.

The last option works correctly, it creates the ESP as it erases the entire disks and proceeds with new partitioning.
