Any idea if you did anything different to get the Creator tool to work? Tried redoing the creator tool twice now. But I'm still getting the "no OS" error trying to boot a brand new USB drive with Unraid 7.1.3 onto an old i7-2600k system. Bios recognizes the USB drive and a couple other HDDs I have plugged in. I've played around with the bios settings a bunch per the help instructions and I either get a cursor just blinking forever or the "no OS" message depending on the USB settings in bios.
