Getting away from Distro-Dell XPS8700-No Boot Device Found

I'm trying to transition away from using a distro and working on installing vanilla. I deleted all the partitions and reformatted the hard drive to start from scratch. I got it installed but now there's no EFI partition so when I boot it tells me that no boot device is found. How to I create an EFI partition again on my main hard drive? Also, has anyone else had any luch with the XPS8700 that can share their config.plist? Everything is stock except the video card which I changed with an old RX460 that I had.

CPU: i7-4770
GPU: AMD RX460
RAM: 16GB DDR3
Mobo: Dell XPS8700
