[SOLVED] Stuck on Installing macOS High Sierra with a forbidden Icon

[LatteCat]

Hi, I have created a bootable USB Installer for the latest macOS High Sierra downloaded from App Store. The version of UniBeast is 8.1. When my computer is booting from the USB Installer, a forbidden icon is showed on the screen.
Could somebody give me some advice?

BTW, my computer can boot normally into macOS from another Solid Disk(NOT a USB Installer), so it's sure the settings of my motherboard are correct. I just want to create new bootable USB Installer embedded with the latest macOS Hight Sierra App.

still waiting for root device error

try a different usb port on your machine (try them all if needs be)

failing that, try another usb stick (usb2.0) plugged into a usb2.0 port on your machine

"Still waiting for root device".
When booting from USB means that your USB flash drive cannot be found.
This is usually because the flash drive is in a USB3 port.
If this is the case move it to a USB2 port, if it is already in a USB2 port move it to another and try again.
Repeat until you have tried all USB ports.
Use a USB2 flash drive.
If it still doesn't work you could try another flash drive.
You might also try enabling Legacy on your USB3 ports in your BIOS settings.
If you only have USB3 ports try with your USB flash drive in a USB2 hub.
Ensure that Fast Boot is not enabled in your BIOS settings.

Great! It works! I plugin my USB drive into a USB 2.0 Port, then it boots success! Thanks~ ^_^
