[SOLVED] Unable to boot unraid with new usb

[MrWuf]

About 3 weeks ago I built a new home server, ASUS AM4 TUF Gaming X570-Plus motherboard, and started a trial of Unraid.  Today the flash drive I was using while initially testing appears to have died.  I already purchased a new flash drive to use after I purchased a license.  I have a backup of my config I used with the Unraid USB creator and am having trouble booting since the prior flash drive died.   

I have 2 USB boot options in the BIOS: 
USB (15.3GB) 
UEFI: USB, Partition 1 (15.3GB)  

 

Booting to "USB (15.3GB)" results in: 

"ExF
Remove disks or other media. 
Press any key to restart. " 

 

Booting to "UEFI: USB, Partition 1 (15.3GB)" results in a blank screen (no cursor). 

 

After the BIOS splash screen, Unraid never actually loads.  The web GUI is not accessible and I cannot ping the server. 

To test: 

• I tried creating the bootable USB with "Allow UEFI" enabled and disabled (though I'm pretty sure it was enabled in my original setup) using my backup. 
• I tried a different flash drive. 
• Tried booting flash drives from different USB ports. 
• I tried a "clean" install, not using a backup, and am having the same results.  

 

Any help would be greatly appreciated.

Try a different flash drive if available.

I did but same results.

See if the flash boots on another computer to confirm where the problem is.

Figured it out.  Turns out the flash drive was in the wrong format (exFat).  Reformatted it as Fat32 and works like a charm.

 

Thank you anyway.
