Still waiting for root device

Hi,

So this is my first time building a hackintosh. I got my bootable clover with Mojave on it and when i start it to start the installation, everything goes smoothly untill it brakes and says: "Still waiting for root device". I have my usb plugged in the right port but i still get the same error.

I've been stuck on this for last few days, and honestly i thought this might be fun project for me, but i got so frustrated that im thinking of buying a MacBook :)

P.s. I've 'stolen' Mojave from my friends Mac
