[NEED HELP] Alienware 17 R3 stuck on boot not loading or prohibitive sign

[iMacintoshPlus1]

I followed the High Sierra guide step by step for installing macOS on my Alienware 17 R3, yet I can't seem to get to the installation screen. I attempted this before almost a year ago with macOS Sierra and got the same result. Any suggestions on how to get my Hackintosh working?

USB:
16 GB with UniBeast and the macOS High Sierra installer downloaded from my old Mac.


P.S.
I know it's possible to install macOS on an Alienware 17 R3 because other people have done it but not shown how.

Follow the Clover guide linked from the FAQ.
http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html

Although you should read the FAQ for an overview of issues, the Clover guide is linked from the first question: "Q. Where do I start?", just after the bold face "Clover Guide".
Here is a direct link, just to be clear:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Also, your profile must be filled out with complete details as requested in the FAQ, again under "Q. Where do I start?". All seven details requested are equally important.

And if you have an issue (after following the guide), or on any other problem, you must provide a detailed description of the problem including information that helps us understand what you're doing. Always attach "Problem Reporting" files as per FAQ.

The required files and data are fully detailed in the last question in the FAQ:
"Q. What are typical "Problem Reporting" files?"
