December 4, 20205 yr Hello, I am trying to boot Unraid in legacy mode however my motherboard isn't letting me. I have an MSI Z390 Pro Carbon and I set it to BOOT+LEGACY. I inserted the USB and when I go to the boot menu and click either the name of the flash drive with UEFI at the beginning or the standalone flash drive name, it always says that it is not a boot media drive and it asks me to insert one. Is there any debugging steps I should take? I've tried multiple different flash drives and it still only works if I'm booting via UEFI. Thanks! Edited December 4, 20205 yr by Advin

I had the same problem with the same motherboard, the solution is to open the USB files, in there you should find a batch file called "make_bootable". Run that as administrator, it will ask you to press a button, enter works fine, after that if everything worked fine just put it back into the unraid machine and it should start right up.
