System wont boot with NVMe drive installed

[DrMacintosh]

Hello Forum,

 

so I just got this Crucial 1TB NVME SSD delivered today. The only way I have to read an NVME drive is through my Thunderbolt 3 Dock, so I connected it and got out my old SATA SSD boot drive and cloned the drive using Macrium Reflect. Once that was finished, I installed the drive, and instead of booting, my system showed the ASRock splash screen (with text saying to press "X" for "Y"), but that was it. The process just got stuck there and nothing happened. 

 

I've tried removing all drives except the NVMe, same problem. I tried formatting the NVMe so it would just be a blank drive and put my SATA SSD back in, same problem. I load the SSD into my TB3 dock and my Mac can read the drive fine in macOS and Windows 10.

 

My motherboard is the ASRock B450M Pro4 running BIOS version 3.50, which is the latest recommended for my R5 2600. Should I upgrade my BIOS anyway? 

 

The common denominator here is my motherboard. Either the Ultra M.2 slot (with NVME support) is dead, the drive isn't supported with my current BIOS, or my config is wrong in a way I can't determine that's preventing the system from booting when this drive is installed. 

 

I wasted a Sunday trying to get this damn thing installed, any tips on what I missed or what I could do would be appreciated. Otherwise this drive is being returned.

Turns out, following my own suggestion solved my problem! Even though ASRock says they don’t recommend updating your BIOS for Pinnacle Ridge CPUs, the R5 2600 is still supported by the latest non beta BIOS (5.30) 

 

Once I updated, I installed the drive and Windows booted! Now I should be able to clone my boot drive.
