Thanks, but I've managed to sort it out. I had booted the memory stick
in non-UEFI mode, then tried
to set it up as a UEFI system, Not being well up on booting with grub
these days, I couldn't remember
how to do that and a couple of trials just produced more errors.

I've now done a complete reinstall booting the install disk in UEFI mode
and it all worked perfectly.

Cheers!

Bill
