Problem install XPe 1.2.0

I am trying to install the new XPe image on my Roadhog console so I have downloaded the .zip file and extract it to a usb stick.

When I put the usb stick into the console and press the F8 button I see the usb stick and the harddisk from the console.

After selecting the usb stick a black screen appears with the message Missing operating system.

Am I doing something wrong?
