No boot device found

So first off I got in a customer laptop that he had a 3rd party repair, as he bought it used, and the morons installed windows onto the 16gb Cache SSD instead of the 1tb drive, I figured ok easy fix, but wait no it's not, windows can install, i can diskpart and clean, i can test with hard drive diagnostics but windows will not boot. When I go into bios and select windows boot manager nothing shows up, it's not seeing the boot manager, and then I go to diskpart and see there is no disk0 just disk 1 the cache SSD and disk 2 the 1tb, but disk0 isn't present, I'm at my wits end with this machine, any quick advice is appreciated 

And quick note i also got the recovery image from the cloud for this system, it isn't bootable either

Well i tracked it down myself, the NVRAM isn't purging properly after a cmos, and HP locked down the nvram from being modified externally with the EFI shell I can't clear the invalid boot entries or even assign a working boot entry. I got it working with a new 1tb M.2 to replace the optane installed 1803 and let windows update it's self to 20H2 and its working now, still a terrible design, why they locked down external access to the EFI implementation is beyond me, and because the system is 3 months out of warranty the only support HP offered was sending it in for a motherboard replacement at 400 bucks, overall my client told me this is the last HP product he buys.

Thank you for not designing a user friendly, or easily serviced product, its working now, but no one should have to work around issues like this based on bad design choices by your company, and your greed. I can personally assure you I will personally steer any customers or friends/family to Dell or Lenovo, heck I'd advise an Acer or MSI before an HP after dealing with this laptop.
