The BIOS has "CSM Configuration", if I go into that I'm offered:-

    Launch CSM
    Boot option filter
    Launch PXE OpROM Policy     

If I disable "Launch CSM" then the other options disappear.  With
"Launch CSM" disabled when I reboot the system it just drops me into
the BIOS diagnostic program and I can get no further.

Similarly if I enable "Launch CSM" and set the "Boot option filter" to
"UEFI only" then on reboot I simply end up in the BIOS diagnostic
program again.

Maybe I should try installing from scratch again with "Launch CSM"
disabled?  (I'm glad this is a fairly fast system!)
