MP 1,1-5,1 Mac Pro 5,1 will no longer boot from NVME m.2 drive

[Jigga Beef]

I have a Mac Pro 5,1 that has been running great. Running Mojove 10.14.6

For about a year I've used a M.2 Evo 750 NVME in PCI slot 3 drive as my primary drive with my OS and its worked fine.

I shut down my machine last night and when I booted it up this AM it would chime but nothing showed on the screen.

I tired to general maintenance, reset SMC and PVRAM and I get a chime every time but a blank screen.

When I remove the m.2 PCI drive and boot from a Bootable SSD in HD Bay 1 the system boots from a CCC back up just fine.

I set that as the bootable drive, re-inerted the NVME drive so when my system booted to my CCC clone it runs fine, and it shows the NVME drive as an external device. I ran Disk Utility First Aid on it and it all seems fine.

I tried to set it as the new Start Up drive and Restart the machine, I get the chime and all but again its back to the blank screen.

So I've confirmed the drive is fine, I moved PCIE slots and that didn't make a difference and the system boots file when a different drive is selected.

Any ideas?

I have a have also tried a new PCIE adapter card as I thought the old card may have been the original issue.

I can see the drive and run first aid in Disc Utility when booting in Recovery mode but when I select it as the Start-Up Drive from there it does not start up, just chimes and a blank screen.

I’m trying to understand your issue, but what is an EVO 750?
Did you tried to remove all other bootable drives and clear the NVRAM 3-times sequentially?

Sorry, the M.2 drive I have is a Samsung 870 Evo.

Yes I have removed all drives and USB connects from the Tower, but can only boot in recovery when the CCC drive is connected.

I am trying to restore it from a TM backup right now. Maybe the OS was corrupted somehow.

I did not try 3 PVRAM in a row, hopefully, the TM restore works but that will be good to know in the future

Samsung 8xx series is SATA, so should be a 970 EVO, no?
Do the 3-times sequentially clear NVRAM process and try again with a clean install to check if it’s a hardware problem or a corrupt install/backup.

I was able to restore from the time machine backup but when I went to restart the computer I ran into the same issue, blank boot screen.

Trying a clean Install now.

Everything seems to be working fine now. Not sure if the Clean install or 3 straight PVRAM did the trick but I am able to use the system, boot from the NVME drive and lost no data!

Which do you have ?

This is a SATA SSD ( can be mounted on a PCIe adaptor or to the cMP SATA port ).

This is an NVMe PCIE ( needs to be installed on a PCIe NVMe adaptor ).

I have the Samsung 960 Evo 1TB with the adapter.

Seems like this Google Update was what messed up my machine but it seems to be working well now.
