Hi Pascal,

When I natively boot off the flash drive, I press F11 to
see what I can boot off of and the flash drive shows up
as a eufi device.  I also have legacy boot turned off
in BIOS., so it would not show at all if it was not eufi.

I have to figure out how to get you recommendations into
my xml file.

Thank you for the help!
