I had an older AMD APU and motherboard setup and the motherboard just died out of the blue.  So I am unable to get a list of previous hard drive placement and do a fresh install.  But that almost doesn't matter because in my testing with a new CPU (Ryzen 5 3400G) and motherboard (ASROCK X570M PRO4) I am unable to boot into Unraid.   * I can't boot using older original unraid USB * I have installed unraid fresh onto 2 different USB's to see if issue with original, can't boot those
