Z640 Workstation SSD OS failure and can't recover

HP Recommended
Z640 workstation
Microsoft Windows 10 (64-bit)

My Z640 workstation has been a solid performer but, recently it developed a non-recoverable SSD "hard drive" fault that took out the Windows 10 PRO operating system.  I am having trouble recovering it so, I'm guessing I am overlooking something simple or obvious.  Here's what I have done and tried:

 

First I removed the SSD (Turbo ZBoost? 256Gb) which let the workstation partially boot.   It does not see the two storage drives attached to the Realtek controller.

I tried a Samsung 980 Pro 1Tb SSD on a card but, that was a fail and not totally unexpected as I don't think the BIOS supports those drives.

Then I tried an older HP branded (Promise) SATA 150 controller with a Western Digital hard drive.  This would not allow the computer to boot and appears to hang up before the BIOS has a chance to send POST error codes.

With neither PCI card installed, the system will load the Windows Setup from a USB thumb drive but, it does not see the hard drive I have installed in the Realtek controller (just one drive so, no RAID).  Do I need to install a driver here?

With the thumb drive removed, it boots normally and complains that no "System disk" is installed so it obviously sees the one hard drive I have installed in the Realtek controller by saying it isn't a system drive.

 

Do I need some driver I can't find on HP.com to load the Realtek driver during Windows installation?  Or, do I need a different PCI card with SATA to get an installation drive for Windows?

 

Thanks!

Sid

use the official HP recovery image (be sure to get the image with embedded drivers) this will require a 16GB usb key

to get the samsung 1TB drive to boot, install drive enter bios and make sure this drive/ssd is the topmost device in the boot list above the  zturbo drive entry

 

the z640 has full nvme boot support and large capacity (over 3GB) drive support when using win x64 10 in GPT mode
