You don't need a license key. The first step to your solution would be to download the Media Creation Tool on another Windows computer, click the Download Tool Now button to get the Media Creation Tool:
https://www.microsoft.com/en-us/soft...load/windows10

Run the Media Creation Tool that is downloaded, have an 8 GB or larger USB flash drive that is or can be erased, and use the Media Creation Tool to create a Windows 10 USB flash drive. Then boot your computer from that. Skip entering a product key, if asked. Select the same edition of Windows 10 you had before (Home or Pro), and you can do a clean install, or with that USB flash drive we can also do some more troubleshooting.

Thanks. I've tried that but I've run into trouble.

If you want to do a clean install and don't have any data you need to save, then delete every partition shown on that disk, click on the unallocated space and then click next.

Thanks! Better than buying a new computer!

When available please post images of the HP tests performed with results.

This is all I got. But I did a clean install with the iso tool. Thanks.

It worked! Then I tried to restore from a Macrium image and it was corrupted and the same thing happened. Very weird. Now I'm getting set up to install apps but am nervous about using that JBOD enclosure to import photos. I can't figure out what happened. Someone above commented on RAID but it isn't set as RAID. I'll ask them. But, once again, mille grazie.

They were disregarded.
You chose to run the old diagnostics 1.09 instead of the newest 7.9.
How come you were unwilling to follow the instructions after posting 3 times?
I'll sign off.

I'm sorry for offending you but you are imagining I have a knowledge base an proficiency I just don't have. I thought I did as you suggested but never did find anything like "Run the extensive > loop until error test >" and still don't know what it means.

But I did manage to do a clean install. But thanks again for your efforts.

Going forward download and install the HP UEFI hardware diagnostics version 7.9.
During the installation there will be two options.
Both can be performed.
Option one is to install on the computer. The computer can be Legacy / MBR or UEFI / GPT.
The second is to install on a flash drive.
The flash drive option will allow you to test multiple computers and consumes little space on the flash drive.
The flash drive needs to be bootable.
It should not format the flash drive.
Then if you have any computer problems you can run the onboard UEFI hardware diagnostics via F2 or F10 or the bootable diagnostics via F2.

If you launch the HP UEFI hardware diagnostics it has an extensive option.
For the extensive option you can use loop until error.
It could perform 1, 2, 3 or more runs overnight.
Click esc the next day.
Run any component tests as needed.
