I currently have Ubuntu 14.04 installed, but I want a fresh start. I am going to wipe the drive and install Ubuntu Gnome 16.04. Unfortunately I'm having no success at all.
I downloaded ubuntu-gnome-16.04.3-desktop-amd64.iso (the md5 checksum matches) and installed it to a new USB drive. My BIOS allows for both a Legacy Boot and a UEFI boot. I've posted the results when I drive to boot both as Legacy an UEFI below. I'm not sure how to solve these issues. I've tried a different USB drive, and different ports.
My video card is a NVIDIA Corporation GM204 [GeForce GTX 970].
Is this possibly a problem with the boot process, the USB, graphics drivers?
Legacy boot results
I get the gfxboot.c32 error. I hit [Tab], then I tried live and live-install. Both result in this error
UEFI Result
This is the screen that is produced. It flickers a bit, then just remains in the image I show here.
