Installation stopped at Apple logo

Hi All,
I recently bought these
Gigabyte GA-Z170X-UD5 TH
Gigabyte Geforce GTX 960
Samsung 850 EVO 250GB
I tried to boot using Unibeast 6.xx.xx El Capitan
The installation stops at the apple logo.
Any help in this regards would be helpful.
Any help for a noob will be appreciated.
