HI there!

I'm having problems with the X570 Pro4 BIOS. It doesn't recognize a pen drive with an EFI partition. I tested it with the P3.30 in several configurations (EFI, Legacy) but I cannot recognize the boot partition. I'm trying the P3.60 bios version too, without results.
I double-checked the pen drive on another computer and it works flawlessly.
In my opinion, it is a problem with the BIOS setting, but I cannot go through the matter.
Some idea?

Bye ALMorgan
