MP 1,1-5,1 Windows 10 booting issues

[natjonesart]

Hi guys, I have Windows 10 Professional installed on a 1TB Samsung NVME on a HighPoint 7101A, Dual X5690, Open Core 0.6.5. I'm pretty much a newb when it comes to Windows but I am finding myself using it more as I have been working with VR sculpting in Adobe Medium via Oculus Quest 2. Windows fails to fully boot about fifty percent of the time, taking multiple restarts before finally loading to my desktop. Once it fully boots, it runs great. It stalls at different points every time, sometimes before login, sometimes after. Sometimes resetting PRAM helps, but not always. It truthfully seems pretty random. Windows is fully updated and the only issue I know of once booted is with thunderbolt drivers. I'm not sure how to even start diagnosing the problem beyond that. Is this common with Windows on a cMP? Any help would be greatly appreciated.

Edit: I should add that I am having no issues in MacOS.

Do you protect your uefi Windows Installation with openCore or alike?

if not you may suffer from Windows certificates in your bootrom / firmware.

protect it with openCore and flash back your rom backup, if you have no backup you should make one with romtool (google romtool dosdude) and let the certificates remove by for example Tsialex.

you can check it with running binwalk on your rom dump. should not show certificates.

My Bootrom is protected by Open Core (I have a rebuilt backup as well)

thats good, have you a current dump and have you checked it?

maybe the protection failed once. As you need to reset the nvram its worth a check.

I'm starting to think this may be a hardware issue with my nvme. If I run BM Speed Test on the partition I can access, read speeds are barely moving, while write speeds seem normal. The file is read/write. The Nvme is a Samsung pm981a that I picked up used last year.

Any suggestions for a good program for checking NVME health?

EDIT- This may not be the problem, DriveDX gives the drive 100%health with no issues

Do you have a guide that you would suggest for setting up Win 10 booting from an 1tb NVME blade on MacPro 5,1?
Thanks

PM981 is not Mac compatible - if thats a hardware issue it is in Windows as well.

I reinstalled Windows and seem to have fixed the issues.

I used the guide in the OpenCore thread.

Hi!

I have same issue. I had my Win 10 on a Samsung NVMe 980 and it worked fine. Then it did not boot at all. I came to the Win start up screen but no rotating dots. I tried do it three times and the "automatic diagnostic and repair" kicked in. But no startup. Then I extracted my NVMe and reinstalled Win 10 on a SSD in bay 1. Everything worked yesterday and at startup to day: No boot again. I tried to set the bootdisk in preference panel in Big Sur but it will not allow it. I get a error " ...the demad can not be executed (SDErrorDomain code 104)
So it is not the NVMe blade.

Can anybody help me, please?
