Updating From Sierra To High Sierra

So I have successfully installed Sierra (10.12) on my laptop and it works fine. I have downloaded high sierra (10.13) from the app store and created an install media using UniBeast however when I am close to finishing installing the loading bar reaches the end and multiple apple logos show up with a multicolored spinning wheel and it freezes on that. Does anybody know the problem or a fix? Thankyou
