Motherboard: Gigabyte X570 Aorus Ultra
Processor: AMD Ryzen™ 7 3800X
I just can't get this motherboard to boot from a USB stick without the CSM support mode.
I'm using is the original Microsoft stick from the Window 10 box. It's been tested on my previous PC and where it boots fine without CSM support. It's FAT32 obviously.
In the new build, once I disable CSM support, the USB disappears from the boot options. It's still detected as I can see it in the USB configuration section, but no way to boot from it. Tried different ports, USB 2.0/3.0/3.1, front panel, back panel, no difference.
Secure boot is disabled, Fast boot is disabled, everything else is pretty much what was configured out of the box. I've even tried flashing to the most recent BIOS (version F11).
I went through a lot of threads but they all suggest a problem with the stick itself (which seems extremely unlikely here) or one of the 2 options (Secure/Fast boot) being enabled, which did not help in anyway. I've run out of ideas at this point.
I could put my old PC back together and use its MSI mobo to install Windows without CSM and then put the drive back, but I refuse to believe that a $300 mobo can't deal with it...
