I've just tried doing what trurl just posted and still doesn't work. I just got back from a trip. I can explain more of my situation right now. when I first was able to boot in the USB with unraid UFEI, I was able to select installation and when it was going through the black screen with words, my cat jumped on my pc and turned off the computer. I didn't know if the installation was finished or it was in the middle, but I wasn't able to boot back into the usb.(When booting up the computer, it doesn't go into anything but goes to my bios like there is no bootable drive. I confirmed that the boot option is set to boot off my usb.) I thought the files got corrupt when the computer was turned off so I formatted and reinstalled the UFEI file again, but it was doing the same thing. I've tried with a different usb and I wasn't able to boot.
