When I try to run the Ubuntu Server 16.04 installer on my USB drive I can get through the language and keyboard dialogues until it says
Error while running 'modprobe -v usb-storage'.
When I hit continue it gives me a light blue screen with a non-functional command line with a black strip at the very bottom. I can Ctrl+C to exit this window but get returned to the error window.
If I hit Esc and wait 30 sec then I get a window saying:
Your installation CD-ROM couldn't be mounted. This probably means that the CD-ROM was not in the drive. If so you can insert it and try again. Retry mounting the CD-ROM?
If I hit 'yes' then it takes me back to the error screen. If I hit 'no' then it takes me to the installation main menu.
