Windows 10 Pro cannot boot after converting MBR to GPT

Hi,

Glad to hear DISM completed succesfully, and please provide the system specs: Motherboard, CPU, Memory, GPU etc...
Thank you for reply @Maxstar.

Motherboard: GigaByte B550 Aourus Elite V2, ver 1.5
CPU: AMD Ryzen 9, 5900X
RAM: 32GB Kingston, DDR 4, 3200
GPU: Gigabyte R9 280 GV-R928WF3OC-3GD
SSD: 2x Samsung EVO 870, 500Gb (for Windows 11 and Windows 10)
Nmve M2, Kingston 1Tb (for data and apps only)
Display: ASUS 24'
 
Do you have another drive or old HDD to clone the Windows 10 installation to? Then we can test some things safely without tweaking files on the current SSD.

Yes, I made disk clone to my external SSD drive, for any case. Booting symptoms are the same. I also copied folder structure to my USB 256Gb also, but this one is not bootable, just copied.
 
Hmm, I was at least hoping that this screen appeared, however which sign-in option do you use? Regular password, fingerprint, pin-code, security key etc...

Local account, regular password.

If I could launch recovery mode, it would ask me for account password and I would be administrator in such environment. Now, I cannot use SFC command since it report error: Windows Resource Protection could not perform the requested operation. The idea was to use SCF to repair possible driver issue, but it cannot be done, probable due do lack of administrator priviledges on some folders and files which SFC uses for repair. The same was with DISM commands which I solve by changing ownership of WinSxS folder from Trustedinstaller to me and it started working. I have also tried DISM++ I got from MajroGeeks to try slipstream GPU drivers, but it did not work also. Finally, I wanted to uninstall GPU drivers to force Windows to use its drivers in first step, just to go to login screen and enter in Windows 10, where I could re-install GPU drivers. I read somewhere that AMD GPU driver have issue with UEFI mode, meaning that drivers needs to be installed in that mode for proper functioning. Before, my setup was in Legacy mode and probably drivers were setup up for that mode, not for UEFI mode.

Bootlog shows that GPU drivers are problem, but it also did not load Windows drivers, which is strange. If we could, somehow put GPU driver inside and make Windows pull it, maybe it would be solution, but how. Just a thought. Sorry to write this long, I have been fighting this black screen issue for three weeks, so far.
 
Is the following file created C:\Windows\Memory.dmp? If so please zip this file and upload it an file sharing site and provide the download link.

No, such file does not exist in that folder. Memory is one month old, brand new DDR4 sticks. I changed configuration recently, booted all up, both Windows in Legacy mode, left it for a week in working condition, installed all new chipset drivers, cleaned leftovers from previous motherboard, everything was working fine, until I made conversion MBR to GPT, UEFI mode, Secure Boot ON. In that environment, only Windows 11 booted and I needed to reinstall GPU drivers since ti automatically picked up some older driver, everything else was good. Windows 10 has never booted to the final point in GPT-UEFI mode. Everything I read on different forums, sites, everywhere I could, is about to use DISM and SFC commands to make it bootable again, but never succeeded in that scenario. Especially with different SFC commands.

I do not play games, not using cracks for software, I bought all licenses for software I use. I am telling here just to point out that I am very careful with possible virus attacks. No attacks I have ever had, so far.

At least, Windows 11 boots all right is usable, very fast and good working, which tells me that memory works. Although this newest 24H2 version broke network sharing as t was before, but I managed to make it work with some way around fix. :-)

Changing hardware without a fresh install is never a good idea and may result in an unstable system! When you are replacing the motherboard and/or other components which do not match with the previous configuration, you should always reinstall Windows from scratch to avoid any abnormalities with drivers.

You may be lucky that the system seems to be stable, but from my own experience you will always run into (unexpected) issues. I know many tweaker will disagree with this and may have different experiences, but Windows is handling old (incompatible) drivers very badly with all sorts of issues.

I know that, but I changed a number of configurations without reinstalling Windows and never had a single problem. It is a matter how do you clean your Windows from unwanted software and drivers, some job to be done, boring, but it is possible. Only if you could boot into Windows. I repaired some Windows booting problems years ago, after configurations change, it is not so compilated, but this time change from MBR to GPT is new thing to me. As I told you, I boot both Windows fine in MBR mode, installed all drivers, worked on them for a week, everything worked perfectly. Now, after this MBR to GPT change, I stucked with black screen with moving Cursors, with high probability it is GPU driver. If we could somehow make Windows 10 to use its driver just for one boot, I would fix all other things. Just a single boot needed here.

I also think that SCF command is needed, but I could never make it work in offline mode. If you check the most recent DISM.log file I uploaded, although it ran successfully it shows that some path are not found also. Maybe, it could be part of solution.

When making such changes, it's highly recommended to make a system image first so you can always revert / restore to the previous state when things go wrong! You can try to boot with the GPU removed from the system, but I don't think it will help in this case.

I do not have spare GPU or integrated GPU. This is the only one I have. Do you have some idea how to solve this issue from ntbtlog.log I uploaded here, it shows driver problem, or is it possible to use SFCfix tool I saw on this forum with prepared list of commands or something other which could make Windows 10 to boot to final stage.
 
To be honest, such driver problems are not really my area of expertise, but I can certainly guarantee that SFCFix will not help to resolve this issue!

Some notes and thoughts:
- When you can boot from the Windows 10 ISO and the Windows 10 SSD you can try to remove the drivers with dism from the image:
Code:
dism /Image:X:\ /Remove-Driver /Driver:<filename>.inf

NOTE: please try this at your own risk!

I tried with care to un-install GPU driver. Result is the same, black screen with moving cursor. Funny thing here is that I can see my PC on network with my laptop and I can browse shared folders, which probably means it booted, but there is no video signal due to lack of GPU driver or something.

That is why I implemented following commands:

Dism /image:I:\ /cleanup-image /revertpendingactions

Dism /Image:I:\ /Cleanup-Image /StartComponentCleanup

DISM /Image:I:\ /Cleanup-Image /RestoreHealth /Source:wim:J:\Mount\sources\install.wim:1 /LimitAccess

All of them were successful.

This command:

Sfc /ScanNow /OffBootDir=I:\ /OffWinDir=I:\Windows /OffLogFile=K:\sfc.log

Returns error.

I am attaching here the most recent dism.log and sfc.log and I see some errors there. Could you please check it out and possible send me some repair solution?

Thank you very much for your time and useful suggestions, I think we shall solve this one.

Hi,

What error did SFC show, this because the result is not very helpful and did not report any corruptions.
 
Please provide a copy of the SOFTWARE registry hive, but sent me the download link in a private message because it contains sensitive data.

X:\Windows\System32\Config\SOFTWARE

Will do when I come home. I used proposed DISM commands to uninstall AMD GPU drivers with aim to force Windows 10 to boot using Microsoft Basic Display Adapter and then I can reinstall AMD GPU driver. The problem here is dxgkrnl.sys which cannot be loaded, which makes make screen goes to black with moving cursor FYI.
