I have been trying to install Ubuntu 14.04 alongside windows 8.1 from a bootable USB. I am new to using a Linux OS. I turned off fast boot option, and I left secure boot on (I also tried off, but then it's stuck on a blank screen rather than this). I have a Nvidia 880M if that is affecting anything.
I get stuck on this screen whether I choose "try Ubuntu without installing" or "install Ubuntu". This text is shown when I am stuck on the black screen.
