HP Pavilion 15-cs1063cl will not boot (3f0)

[my_3f0_error]

The computer will not boot. The error given is:

Boot Device Not Fount

Please install an operating system on your hard disk.

Hard Disk (3F0)

Based on https://support.hp.com/us-en/document/c01442956 I was directed to https://support.hp.com/us-en/document/c06201699. 

I completed all steps on this troubleshooting page:

1. All tests using the HP PC Hardware Diagnostics UEFI utility passed

2. Legacy Support under Boot Options is DISABLED

3. Optane memory IS installed in this laptop, but it is not detected.

The solution presented on the page is to contact HP customer service; however, this product is out of warranty. So, I have been unable to reach any HP support personnel. I have tried the Virtual Agent, but it cannot find a solution and suggests that post in the HP Support Community.

What are my options at this point?

And then some properties of the disk.
