I've created a 15.10 Ubuntu USB drive and booting off it with an ASUS Rampage IV Black Edition motherboard, I get:
Ignoring BGRT: invalid status 0 (expected 1)
and then nothing. I've become really frustrated trying to get a stable BIOS config with this motherboard (every boot produces an Overclocking failed! message and none of the even low-key default options avoid this message with an i7 3930K – this board rules as the hardest motherboard I have ever configured in the last 10 years!) and now it can't boot a vanilla 15.10 USB drive. I'd really value some help..
EDIT
I found the solution. See below.

As an alternative to waiting, add the boot parameter
nomodeset
to grub during boot. This can be done by pressinge
on the grub menu entry and then insertingnomodeset
on the Linux line.This seems to be a problem caused by the most recent kernel and Nouveau, not Ubuntu.
