Having an issue after getting a new CPU and MB for my unraid server. The system won't boot into the OS. USB is correctly detected in the UEFI and I set the boot priority and even tried a boot override but it just won't post. I put the unraid usb drive into my main system and am able to boot into Unraid no issues.
Old System: Intel 3700k + ASUS P8Z77 WS - Boots fine
Main PC: AMD 5700X + ASUS Crosshair Hero VI - Boots fine
New System: Intel 12400 + MSI Z790-P - Won't Boot
I tried disabling fast boot but it had not effect. If anyone has any other suggestions I'm down to try them before I just return the board.
