Ubuntu installer and UEFI

[Volker Wysk]

Hi

The Ubuntu 18.04.3 installer seems to not support UEFI. It creates no
EFI System Partition (ESP), and doesn't make a protective MBR. It looks
like it supports MBR only. I've just used the default, "format hard
disk and install ubuntu".

This can't be, can it? Or is it because Ubuntu 18.04 is too old?

How to tell the installer to make an UEFI system?

puzzled,
Volker
