Win 10 will not load. Completely stuck

Restart your computer then execute those commands.

After restart, I got this

Type Cd /d X:\windows\system32 command and press enter key.

Execute BootRec /FixBoot command.

Failed. Did I type this wrong?

I don't understand the System partition is healthy or we would never able to execute Chkdsk command for the System partition.
You did execute Chkdsk command for D:\ partition haven't you?

Windows Vista/ 7/8/8.1/10 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.


Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.


Please type below commands into Command Prompt and for each command you have typed press Enter key.

Code:

Ren  C:\windows\system32\config\SAM         SAM.BAK

Ren  C:\windows\system32\config\SYSTEM      SYSTEM.BAK

Ren  C:\windows\system32\config\SECURITY    SECURITY.BAK

Ren  C:\windows\system32\config\DEFAULT     DEFAULT.BAK

Ren  C:\windows\system32\config\SOFTWARE    SOFTWARE.BAK

 

Copy  C:\Windows\System32\config\RegBack\SAM         C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SYSTEM      C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SECURITY    C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\DEFAULT     C:\windows\system32\config

Copy  C:\Windows\System32\config\RegBack\SOFTWARE    C:\windows\system32\config

This procedure assumes that Windows Vista/7/8/8.1/10 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.


Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.

Thats what I don't get. It seems to be fine, but it won't boot. Puzzling. I'll try the above commands and let you know. Stand by.

So my commands should run like below? Should I receive a response from the system after each command?

Yes you have executed Ren command correctly.

OK I'll continue and let you know

Ren Commands completed. Now executing COPY commands
