just got this board. Im using HIVEos on a USB drive. The drive work on my btc pro board so the usb drive isnt the issue.
I cant boot the usb drive using this motherboard, it just stays on BIOS.. I have the USB drive as boot option #1.
I need help figuring this one out
You have probably figured this out already by now, but if not... you need to disable secure boot - set to "Other OS".
To disable secure boot, you first need to disable CSM (Compatibility Support Module).
I don't have my BIOS in front of me right now, but I am sure you will find both of these by browsing around

Have fun!
