Hi all. Long time forum veteran of many Internet forums, first time posting here. This weekend I decided to start an upgrade on my GA-Z170X Gaming 7 motherboard. Was adding 2 new M.2 nVME drives and a faster memory kit. Hardware install went better than I hoped. Machine powered on and properly posted. New memory set to XMP profile without a hitch. I am however; running into 1 big caveat: the motherboard in question using the latest BIOS revision (F22m) will not recognize my bootable Windows Setup USB flash drive. Now, it's been years and BIOS revisions ago (F6 was when Windows was installed last) so maybe I am missing pieces of BIOS configuration that would allow the motherboard to see the USB flash drive. When I flashed the BIOS from F6 to F22m I did do that by the book and Loaded Optimized Defaults after it was done. I am recreating the Windows Setup flash drive I have by the book in case I messed that up when I upgraded it to install the latest Windows 10 build 1909. In any event, what needs to be set in the BIOS to get the flash drive to be read as bootable so I may load Windows? Write back with any answers and advice. Thanks and until next time I am out!
