Using BIOS F9gPuzzling...
- Which version of BIOS are you running? F9g, F9i, F9j?
- What is the make/model of your USB flash drive?
- Which USB port is it connected to?
- Other than macOS, which other operating systems are installed?
- Have you tried CMOS Reset (which requires configuring BIOS parameters again, starting with F7 to Load Optimized Defaults)?
Using a MicroCenter USB 3.1 32GB stick
Using Blue USB 3.0 Port
No other OS's installed
No on the CMOS reset.
I was going to try another USB still and different port next.
