After it is done, it restarted, still select USB installer but select boot from newly installed macOS Sierra. The first is preparation of disk about 5-7 minutes, then it restarted, you must select USB installer again, make sure it boot all the way through and real installation begins will be about 16-18 minutes. By using CreatInstallMedia method, the installation is a 2 step process. I use Slice FakeSMC & the latest Clove 3625 bootloader. I did my macOS Sierra Public Beta createinstallmedia method. When building a bootable USB stick for an install, there are other files that need to be transferred over that the normal 'createinstallmedia' method does not do. This method will not work on a hackintosh that's why.
