Hi,
I recently decided to make an upgrade and got new mobo and CPU. The upgrade was from an Asrock Z370M Pro4 to an Asus Z790M Prime Plus D4 plus a new CPU.
Previousy I had my Windows in an nvme drive and that worked great on old pc. However when I put the windows drive to the new motherboard, it doesn't find any windows installation disk!! While using a USB Windows setup key I can use the command prompt and see the files of the nvme windows drive are still there. However windows cannot find any windows installation there!! Any idea how to fix this?
How can I repair this drive?
Furthermore there were several restore points in my disks but Windows setup key doesn't find any...

thanks
 
While booted from the USB select the nvme drive and list partitions

Diskpart
List disk
Select disk ?
list partitions

This should show what's missing. Fir GPT you only need two partitions. We can recreate any missing partitions and copy the bout files over.

I'll reply in the morning with the steps
 
ok made some progress and nvme is finally recognized as boot drive thanks to this link:

Problem now that I get a blue screen saying that my windows drive needs repair as it cannot find the winload.exe
 
This is the message I receive now:

Your PC couldnt start properly
The header checksum for this file doesn't match the computed checksum
File:\windows\system32\winload.exe
Error code: 0xc0000221
You will need to use recovery tools...

Thanks I am creating a windows boot usb key with Rufus. Maybe it will prove useful
 
Good morning! I finally managed to enter my windows disk, but there are still errors. Intel me or intel drivers cannot be loaded and in device manager there are several not installed items (usb etc). I tried to update the ME drivers but get a fatal installation error and when I tried updating through the intel app I got a blue screen.
 

That's what I used to stop Windows 10 upgrading itself say from 19H1 to 21H1 - I don't see why it shouldn't block Windows 11 updates either. You might need to repeat it a couple of times, but I always found removing the update files with BleachBit before restarting Windows stopped the update in it's tracks too - just make sure you use the above software to block the update as soon as the machine is restarted.

You had older Intel ME 11 drivers installed that only worked for your old motherboard Asrock Z370M Pro4 with old ME 11 firmware, they both cannot be update to latest ME version so it only worked with version 11. Your new motherboard Asus Z790M Prime Plus D4 Plus used Intel ME version 16 drivers and firmware so it best to uninstall ME 11 drivers then download and install ME 16 drivers and update ME firmware to latest version.

Had to deal trying to hide some Windows updates myself recently and found wushowhide a bit lacking so i gave...
A go and found it to do a much better job WRT hiding updates, if you know the KB article number before running Windows update it's just a matter of opening a powershell window and typing 'Hide-WindowsUpdate -KBArticleID KB4023057, KB5001716' or whatever the KB number is.
 
Hi again,

I managed to use an older restore point and I am back into Windows... for a while and again another blue screen. There is no way I can repair those flies/disk and now decide to install Windows 10 Pro to an older SSD disk I had and at least test the system from a hardware perspective. If that goes succesfully and Windows run well on this disk, can I check the older Windows drives?
 
Well it seems, the solution was just in front of me... I was suspecting the memory, as the errors were random and also had the impression that they were less at 2133. So I checked the manual again and voilaaaa!! I had put the memory dimms on the wrong slots. I also upgraded the bios to thelatest one and everything seems fine so far...
