Cant install Yosemite. Stuck at boot

Hi all.

Config- Intel Pentium G4400 R9 380 2GB 24GB RAM 250 GB HDD 60 GB SSD Asrock XA1 Z170 Mobo

Used Uniboot 5.2.0 to setup Yosemite (As per tutorial).

When I plugged my pendrive (16GB USB2.0 Sandisk Cruzer), it showed

Boot0: GPT Boot0: pass Boot0: passZZZZZZZZZZZZZZZZZZZ(@

And is pretty much stuck there. Any leads?
