Hi turtleinarock, I upgraded from a similar versions in X870E Aorus ELITE WF7 ICE when moving from F7 to F10a. To get bios to view the bootable unraid usb: Enable CSM, Disable storage boot option control. I believe this just disables the checks for UEFI or Legacy. Not really sure howGigabyte classifies those bootloaders. (Optionally disable PCI Device ROM Priority?) I disabled mine. I doubt it matters for the bootable drive. The unraid bootable will appear as "USB".
