This is what I did, I was going to buy the unraid license, and I found out that the usb drive I was using was blacklisted, and won't register.  So, I decided to switch the flash drive for another.  Since, I don't have a license, I just copied all the files from the original flash drive to the new one.

 

I plugged it in, and it won't boot up.  It just stays on the black screen.  I tried to rearrange the booting priority, and I get an error message of: "remove disk or other media" "press any key to restart"

 

I am using the biostar a760g m2+ and Unraid 4.7 free (3 drives at the moment, but need to add two more)

 

Thanks for any help!

I plugged the usb drive, which I had before, and I was able to boot my unraid server with it.  So, I've googled, and read other post on this forum, but I can't find a guide on how to switch your usb drive so I'll be able to register to get a license.

 

Thanks for any of your help.

 

I am trying to use a Lexar Echo micro usb 8gb flash drive.

I found the soloution, I forgot to run make_bootable prior to plugging it in the usb port of my unraid server.
