Thanks GTiceman - I have ATI 2014 and 2015 so all should be good.
ETA -All is not good - tried ATI 2013, 2014, 2015 USB - booted to USB OK - showed this:
2013-2014
Starting Acronis UEFI Loader...
Select an item by using the keyboard:
1. True Image
c. Continue Booting
2015
Starting Acronis UEFI Loader...
Select an item by using the keyboard:
1. True Image
2. Acronis System Report
c. Continue Booting
Pressing "1" or "c" does nothing, leading me to believe that the keyboard is not active at this point in the boot process - OR - I have somehow turned it off - I love learning new things...
Next week I may try marriage...
