Dell XPS 15 9560 Won't Boot from USB

I am struggling to boot from USB.  I need your help!

I have a 2017 Dell XPC 15 9560.  

BIOS 1.19.2

I have run Diagnostics and have a hard drive error.  A replacement NVMe drive is on order but I need to be able to install a new version of Windows 10.  So I am trying to boot the laptop with a USB.

The ePSA Pre-boot System Assessment [4306.17] gives me green lights on everything except the drive.  ("Hard Drive 1 - S/N ES78N646910108Q1Z, incorrect status = 8000000000000007     Could not read DST log page"  or usually  "Validate Code : 120160 Hard Drive - Not installed".)

I have entered the BIOS and turned off secure boot

I have Enabled legacy boot mode.

When I start the computer and press F12 I get the option to "Legacy Boot: USB Storage Device".

When I select that I receive the message, "Selected boot device failed.  Press any key to reboot the system."

I created the recovery USB after downloading the Dell Recovery & Restore software and inputting my Service Tag.
I thought the USB must be corrupt so I went out an bought a new one.  Same results.

Is there another way to create a Recovery USB?  Am I missing something?

I have also tried to UEFI boot with Windows Boot Manager (hoping that it would give me option to select Boot From USB).  SupportAssist launches runs a system scan and states, "No hardware issues were found..."  I choose 'Continue' to launch Support Assist OS Recovery and just get a blue screen and then after a minute the computer shuts off. 

Any assistance would be greatly appreciated.
Thank you!
