Need help with hackintosh build

So I am following the tony x mac follow through on high sierra, all steps go to plan until OS is installing and system reboots once half way through, I try to boot off UEFI USB(High sierra installer) and all I get is a blank screen with a pulsing underscore, and I try to boot off of the target drive and its saying nothing is there. Now I don't know what to do..

Specs are:

CPU: i7-4990k

CPU cooler: Corsair hydro

motherboard: MSI z97s sli krait

Ram: Corsair dominator platinum 2 x 8gb

GPU: MSI GTX 1070 AERO

PSU: Corsair 550 something gold

SSD: WDS250g (Windows 10)

USB: Sandisk 16gb (Installer)

Portable hd: Seagate BUP 1T

Thanks for any effort
