Unable to boot neither with legacy nor uefi mode – General Support

I was about to try unRAID on my HP ProDesk 400 G5 with the trial license. I specifically bought the recommended Sandisk Cruzer Fit (32GB), but I only have a USB 3.0 port available for the drive to boot from.


I used Unraid USB Creator (Win32-1.8.exe) to create the boot drive (unRAID stable 6.10.1).


However I can’t boot to unRAID. When I attempt to boot in UEFI mode, I only get a BIOS beep and am directed back to the boot options. I then re-enabled legacy mode and attempted to boot in legacy mode I get the message that the chosen device isn’t a boot device.


Are there any BIOS settings I could try or another approach of creating the USB drive?
