Windows 10 processor not supported after Bluetooth upgrade?

[Partridge]

This is a weird one.

I have a 5,1 Mac Pro that was quite happy running high Sierra off of a PCIe ssd and Windows 10 off of an internal hard drive.

I recently did a Bluetooth/wifi AC upgrade and now when I try to boot into window i get a blue screen with the error processor not supported.

My first thought was that it had something to do with a windows update and the vid card, so I reverted back to my old 5870. No dice. Tried pulling all the other PCIe cards and drives leaving just the windows drive. No dice. Tried pulling the windows drive and just booting off of the windows dvd. Even that gives the error.

At this point it feels like it has to be the WiFi card but that makes no sense. I guess my next step is reverting it to stock.

Has anybody had anything like this happen? I don’t see how it could be the actual processor. Everything runs just fine in OSX.

The WiFi Bluetooth upgrade works fine in OSX. 802.11ac speeds and handoff working as expected.

You need to reinstall Windows.

You need to reinstall Windows.

I can’t even boot off the windows DVD that I originally used to install it the first time. Same error.

Figured it out.

Windows did NOT like the processor microcode replacement at all.

Reflashed to stock and it booted up perfect.

It's a bit sad to say that this "processor not supported" BSOD is somehow expected after perform the microcode update. But I can still boot from the DVD and perform a new Windows 10 installation with 0085.B00 firmware microcode version 30 and W3690.

I tried both legacy and EFI mode, new installation work. Did you try the latest ISO from MS?

I’m on the 0087 firmware.

Something about updating it to have the newer microcode seems to have tripped windows up for me. Not sure why. It was running perfectly on OSX. I’m back to stock 0087 with no microcode now.

The fact that it won’t boot from the windows DVD(yes, most recent ISO from Microsoft, burned it myself) is what I found weird.

Thanks for the report and sorry about the inconvenience caused. I am still waiting to test the 0087 BootROM with microcode injection yet (my cMP still need another day to finish all the queued process). But now it seems you save my time.

I will update the microcode post, and warn all other members about the possible processor not supported issue.
