It's "UNRAID" sry
I was running Windows 10
I tried 3 other USB sticks in 4Gb and 8Gb, but its not finishing on every stick beside the stick I used before
It's a San Disk Ultra USB 3.0 32GB plugged in to a USB2.0 port.
It's created using the Unraid creation tool and labeled "Unraid".
During the boot there are some reports like "USB1 not mounted; USB2 not....".
I will try another stick.
