Issue with upgrading unraid box

[Pandemic]

I've been an unraid user for the past 7-8 years and it's typically run quite well. I've updated my old core2duo machine to the following:

i3-10100 cpu

Gigabyte z590 ud ac motherboard

32gb ram

Same Supermicro AOC-SASLP-MV8 x2

15 SATA bays

 

Now, I'm having a massive issue configuring the motherboard to boot from the Unraid USB. I've tried legacy support but nothing is successful so far. Do I need to focus on anything regarding the Unraid USB drive or is it all motherboard BIOS specific?

Have you tried booting in UEFI?  Rename the EFI- folder on the unRAID USB flash drive to just EFI (no '-' character at the end).  Also in your BIOS you may need to specify UEFI:[name of flash device} as the boot device instead of just {name of flash device}.

I removed the "-" and it seems that did the trick - thanks for that advice!
