[vega]

hey guys

i need help i recently did a fresh install of el capitan using unibeast/clover during the installation i used the nv_disable=1 bootflag. now i can only boot using nv_disable=1 or i get no signal after the apple boot logo.
I have a gigabyte ga-ep43-ds3l mother board with gigabyte geforce 9600 gt graphic card, system deftinition MacPro 3,1.
i have used ML and Yosemite on the same configuration using Multibeast.

this is what i get when i boot on verbose mode ithout any flags:
