Stop sign after booting high sierra (Newbie here)

So, as i said i installed high sierra with clover in an ssd and everything was fine but when it restarted and i clicked in the menu boot macOS it just shows the stop sign.

I have the right kext i think, also used one for the NVIDIA fix, intel ethernet, audio and usb injector and also the generic usb.

My build is the next one: Motherboard : Asus Maximus VII Gene, GPU: GTX 1080, CPU: Intel Core i7-4790K, RAM : Kingston HyperX Fury Black DDR3 1866MHz 16GB CL10. Also im using two ssd, one for windows and the other one for MacOS and then im planning on using the clover bootloader.

Thanks to all!
