After it was done installing I shut it down then re-enabled 2d and 3d for display settings with 256 MB display memory. Started Windows 10 back up and installed Guest Additions without needing to set it in compatibility mode.
I notice that you could not choose the 2d or 3d check mark boxes during the Guest Additions installation. But they were already checked and dimmed to were I couldn’t change them. Thats okay, at least they were checked. After installing the Guest Additions, I rebooted. When 10 started back up, the display driver worked.
Device manager said the display driver for Windows 8 was working fine!Thanks!.
