I just installed Windows 10 RTM on my VirtualBox and I wanted to install Guest Additions. I inserted virtual CD with it and during installation the graphics crashed and since then (even after reboot) I can only see a black screen. I'm reinstalling OS but how can I install properly Guest Additions? My computer is running on i5 4th generation (if that's relevant) with it's integrated graphic card.
P.S. I'm not getting any modals with errors.
