1. Switch to the Security page and disable the Secure Boot.
2. Switch to the Boot page and enable Launch CSM.
3. Is SanDisk Cruzer 8.02 list in the boot menu?

1. Yes I have disabled the secure boot.

2. I don't have Launch CSM option.  Do you mean Launch EFI shell or?

3.  Yes the SanDisk Cruzer 8.02 does list in the boot menu but when I select it I am ignored, it just bounces over it and boots straight from the main C drive Win 8.1 again.

It seems  that your motherboard don't have UEFI CSM mode, so it can't boot from MBR-based USB flash drive.
I recommend using a USB hard disk or a Windows To Go Certified Drives to create Windows To Go.

I have tried the whole process with a USB hard disk but it is the same problem, it cannot boot from this either. When I try boot override it just flashes to a black screen then back to the boot menu but refuses to boot. There is something in this device that is programmed not to boot anything at all from USB unless it is a windows recovery drive.

I guess another thing to watch out for when I replace my main computer.
