trouble installing Mojave

Hello. I have been trying to install mojave onto my machine. It appeared that it installed without issue other than pink horizontal lines across the screen while installing on the apple logo screen.
When I try to follow the next step of booting from usb and then choosing the new mojave install, nothing happens. totally frozen on Apple logo screen. So I never get to the step of running multibeast.
Can anyone help in finding what I am doing incorrectly?
Thank you.
