I boot from USB and still I'm getting *Reboot and select proper boot device...

Hey everyone, this may be in the wrong place, so apologies in advance if it is. Basically I've bought the ERE system for windows 7, followed all the instructions for creating a boot device on a USB which seems to have everything looking right. I've plugged the USB into my windows computer and select to boot from that USB and still, I'm getting the same message, "Reboot and select proper boot device or insert boot media in selected boot device and press a key".

Any suggestions as to what I may be doing wrong or do I need a refund? If so how do I go about processing that?

Thanks in advance

Luke
