I had the same. but i waited a while (when black screen showed with only the arrow) Later if started, but not perfect, there where no icons on the taskbar and open windows didn't show there to, after a reboot, everything was fine.
Does anyone have this installed in Oracle VirtualBox, because my installation keeps BSOD-ing randomly. At first, in previous version-build, didnt show me that there is the update, so i updated it by downloading esd-convert to ISO-installed as upgrade.
^yep I am running it successfully in a Oracle VM. You do the following: 1. Enable 3d/2d acceleration in machine properties - Display 3. DO NOT install oracle additions in the guest OS. Otherwise it won't boot and you have go to the safe mode to uninstall additions. That's it. Everything else works like a charm.
1. It is enabled. 2. Is that new for this build? Because I have always installed it without any problems, and I need it for shared folders from host OS.
This new build brings the compatibility issue to additions. So they just do not work properly in 14986. That's why you have to not install them.
