I am starting a project under Linux and have difficulty with installation on Virtual Box. I have no idea why during the installation, the following screen shows.
VirtualBox: 5.1.6 version
Ubuntu : 16.04.1 Desktop i386
Try these options:
Install Ubuntu on a different host OS.
Wait a bit (when I see that garbage, it disappears in 10 seconds.)
Try to install a different guest OS, or a different version of Ubuntu.
Press Right Ctrl + F1, then Right Ctrl + F7.
This will reset the graphics adapter, first into text mode (TTY1), then into graphical mode again (TTY7).
