My boot usb drive was failing a few months ago.  I was able to repair it in Windows.  I took a backup and it was running fine.  It failed again and I was not able to see it in windows so tried to create a new one using he unRaid usb creator tool.  I have tried two different USB sticks, one was the same make/model as the original.  I have tried creating from the backup using the tool, tried to copy the files and use the make bootable .bat file, and tried creating a new one from scratch without the backup config files.  I have tried plugging into all usb slots on the motherboard.  If I enter the boot menu (F8) the drive shows up and I can select it as well as setting it in the bios.  Nothing I have tried will boot from either stick.  I only see a flashing cursor on a monitor I've attached.  The ip address does not show on my router and I can not connect through telnet.

 

Any ideas what I should look at next?

UEFI or Legacy?

I've tried both.  If I try UEFI from the boot menu it just brings me to the bios setup

 

If booting UEFI, folder on flash must be named EFI

If booting Legacy, folder on flash must be named EFI-

 

 

 

If I remove the dash from a manually created drive it starts in the UEFI bios screen.  Using the check box in the usb creator tool removes the hyphen automatically. Then I just get the flashing cursor.

Also, be sure to boot from USB2 port.

It's booting now.  I may have missed a step in the UEFI setup, or at least I hope that's what happened.  Creating a new one using the check box again failed to boot but for some reason in the setup it was showing one of the array drives as the first boot option now.  It had 2 options listed for the usb drive and moving the UEFI one to 1st allowed it to boot.  I'm almost afraid to try creating a new stick from my backup now that I've gotten this far but guess I need to.  

 

Thanks for your help!
