Thanks Jonathan.

You're probably right about this as whever I try to do makes has effect.

I've been looking in to efibootmgr to see what I need to do to get it working but so far with no luck. 

When I run it with -v I don't see any UUID details, nor can i see how I specify them.  One thing I have noticed is that in the blkid output below everything refers to HD(2,...... Is that correct?

Below is one of many attempts to set the values correctly.
