No Boot device is available, press enter to continur

I have been trying to get my Parallels working on my mac for a couple of weeks now...

The issue I have is I have installed Parallels to point at my bootcamp partition (on the same mac) however at startup I'm getting the message above.

I have two macs both running Parallels, one with a 480GB OWC drive and one with a 980GB OWC drive, the 480GB works fine but the 980GB gives me this message.

Both have Use EFI unticked, both pointing at Sata 0:1

I'm at a loss.

Any help or advice would be greatly appreciated
