@nrbrtx (Norbert) Ok. Also, just to be extra clear, "Enable EFI" was NOT selected in the VirtualBox settings, and the host machine is also with old-style BIOS (no UEFI at all).
#1: Do I have to create two small partitions, (1) EFI system partition, and (2) Reserved BIOS boot area... or just one, EFI system partition? #2: From the link you provided, point #11 says, "Full drive space is allocated for installation" So does manual partitioning (meaning not allocating the full drive space) blocked / not allowed anymore with Ubuntu / Ubuntu MATE 20.10 onward?
