I've been trying to install elementaryOS LUNA 64bit on my machine. I am currently running Ubuntu 14.04 64 bit without any issues. When attempting to install from a usb drive I get 'NO DEFAULT UI OR CONFIGURATION DIRECTIVE FOUND'... I tried fiddling with the file names from isolinux to syslinux with no avail.
I've burned both the direct download iso's and torrents to dvd and got a little farther but it fails with this error.

I was directed to try installing the 32bit version and that failed as well. It hangs at the initial install screen.
Machine stats:
ASUS P5N32 board, Intel® Core™2 Quad CPU Q6600 @ 2.40GHz × 4, 4gb ram, nVidia GFORCE video card.
Like I said, everything works perfectly fine in Ubuntu 14.04 *64* BIT... Not really sure how to resolve the issue.
