Hey Gang -
New install here on a SuperMicro board, same error message as reported in this thread.
I'm using the latest UnRaid build, 6.4.1 and have tried several USB sticks - no joy.
I changed various settings in the BIOS (Legacy OpROM to UEFI Only, various USB settings also) but no change. Only way I got it to work was to install 6.3.5 instead.
Does this mean I am stuck with regards to being able to upgrade to future versions of the software?
Thanks
