I downloaded the Ubuntu 16.04 i386.iso file from the website and tried to load it on the VirtualBox but it does not get installed and displays this window. Can someone help?

  • If you're asking then you didn't :) virtualbox.org/wiki/Downloads Select the package according to your Virtualbox version. The host OS doesn't matter in this case, the Extension Pack is to be opened by the installed Virtuabox itself. Install it and try again, change (improve, recommended) the graphics settings if needed before running the installer / live session.

As memory serves me, switching TTY's should fix the problem.

To fix your video problem, hit the host_key + F1, followed by host_key + F7. It's a bug.

On a Mac, you may have to host_key + fn + F1 and then host_key + fn + F7
