"The installer encountered an unrecoverable error" message when booting

[Wise Melon]

I downloaded the Ubuntu GNOME 16.04 Beta 2 http://cdimage.ubuntu.com/ubuntu-gnome/daily-live/20160322/xenial-desktop-i386.iso image, launched it in a VM, waited, got to a black screen where my mouse was visible and then got this:

When I clicked "OK" and it took me to the desktop session it promised I was not able to launch Terminal through any means (keyboard shortcut and Activities Overview). I had to collect the information for this report using a TTY which I luckily was able switch to. Though I found that other applications such as apport and Firefox would run.
