Comment 10 for bug 1445592

Brendan has Step #2 exactly correct:

"Select "Install" (not "Try before installing")"

I've tested both the Ubuntu GNOME and Ubuntu 20150417.1 amd64 images on bare metal and if the installation is started from the live DE all works as expected, but if you you choose Install while the image is booting restart fails once the install is complete.

The prompt to restart is displayed but after clicking on restart the disc ejects as it should, then the screen goes black and no key combination will complete the restart procedure.

So it's sort of a combination of bug #966480 and bug #1436715 with the exception that all works well as long as the installation is started from the live DE, but if install is chosen while booting the images the post-install reboot process is borked.
