This has been a problem with Ubuntu since forever - when booting in VirtualBox, the installer expects higher resolution than what is available and there is no way around it except trial and error tabbing ahead. There are apparently some minor differences between 20.04 and 21.10 install dialogues, so I just spent ten minutes blind counting tabs to see if I can coax it through. You can forget all about any customization, it’s a battle to just get it to take defaults.
This fails so incredibly hard …
