Salve a tutti,
vorrei installare su una macchina virtuale che gira su Windows 10 la distribuzione linux: Elementary OS, che sarebbe una derivata Ubuntu.

Appena installato tutto, la distribuzione si avvia in una risoluzione bassissima.
Temo che sia dovuto alle Guest Additions.
Ho provato a installare VBoxGuestAdditions_5.0.16 ma ho un errore

codice:

Come posso fare per installare queste maledette Additions\VBoxGuest.inf e visualizzare linux nel formato corretto? devo procedere da dentro linux? Cambi software anzichè usare virtual box?

Vorrei trovare la soluzione più facile per avere la distribuzione linux virtualizzata correttamente.
Grazie anticipatamente.
