Unable to Boot from ASUS B250 Mining Expert

[antireed]

Hello,

I just purchased an ASUS B250 Mining Expert Motherboard, but am having a lot of issues booting from it. The BIOS just isn't recognizing the USB drive I'm trying to boot from (SMOS), nor is it recognizing the SATA SSD (Windows) either.

Pentium G 3930 Celeron Processor
8 GB RAM
750 Watt EVGA Power Supply

Something new about this board are the "book keys" located in the boot option of the BIOS. This is foreign to me. Do I need to load some sort of file onto the drive I need to boot from before the motherboard will allow me to boot from it?

I just turned CSM on and now the screen just goes blank. Any recommendations? Any help is appreciated.

I switched out my motherboard to the ASUS B250 and am having boot issues as well. The motherboard can see and boot from my windows SATA connected drive but it can not find simplemining OS USB drive.

Any bios tips would be appreciated.

I’m having few B250 Mobo they run mostly without an issue. I had occasional boot up issue but they were all temporary and vanish when I get into BIOS set up (function key + F1) and simply save the setting ( function key + F10) without making any changes and boot again.
