Can't boot

[mysticalsuffix]

I'm brand new to this.

Build: -Gigabyte GA-X99 UD5 Wi-Fi
-16 GB Ballistix DDR4 2400 UDIMM 1.2V (Though I can only get power to run with only 8GB installedwithout the power shutting on and shutting off over and over endlessly).
-EVGA Geoforce GTX 750
-i7 5820K LGA 2011 V3 Hex-core
-Samsung SSD 850 EVO 120GB
-H100i water cooler
-Corsair CX 600M power supply
-Corsair graphite series 760T Full tower

I did the Bob Roche method using Unibeast and added the necessary kexts. I installed to a GUID drive and then used Carbon Copy Cloner to an MBR formatted boot drive. I then used Multibeast and I screwed it up because now it won't boot. The boot flags I used were: GraphicsEnabler=No npci= 0x2000 nv_disable=1 -f -x

I'm planning on using this mainly for a DAW with multiple MIDI plugins in cubase. Orchestral works for video games and the like.

Please help!!!
