@Tom-Elliott The only issue I see is that what ever utility the OP has to change the bios boot order, it has to be a linux program. I know off the top of my head, dell and lenovo have windows/cmd base versions of these programs. If the FOS kernel was based on winpe, then there would be a higher chance a program would exist. I use the Dell Command and Configure to change the boot order with my bios update flash drive. So I know its possible at least with Dell business hardware.
