[solved] HP Spectre X360 -13t Coffee Lake won't boot from internal ssd

[grassmudhorse]

I'm finding a lot of info on how to hide Preboot and Recovery from the GUI when searching for "Preboot.efi solution." I tried it for kicks but it makes no difference.

Is there something more specific I should be searching for, or perhaps a specific thread I should follow for this?

I asked around and fount it! It is called Preloader.efi from Linux. See the below guide, step 5 and 6.
