Hello
have you tried to repair it by using the DISM commands?
Analyze the Windows 10 image with DISM
Open a command prompt as an administrator.
Analyze the Windows 10 image to determine if it is damaged or not:
Quote Dism /Online /Cleanup-Image /ScanHealth
This operation may take several minutes.
You will get one of the following results:
"No damage to the component store has been detected"
it's perfect, the Windows 10 image is intact! 
You can run the command : 
Quote sfc /scannow
but at first sight it is not your case
you probably have the message:
Quote  The component store is repairable

 this indicates that the image of Windows 10 is damaged.
So you have to check if the image of Windows 10 is intact, repairable or not repairable:
Quote Dism /Online /Cleanup-Image /CheckHealth

If the image of Windows 10 is damaged but repairable
Repair the Windows 10 system image:
Quote Dism /Online /Cleanup-Image /RestoreHealth
If everything goes well, you should get the message
Quote "The restoration was performed. The operation was successful".

the Windows 10 image has been repaired successfully!
if you get an error message:
Quote Error 0x800f081: "The source files cannot be found".

you have to repair it with the ISO of the version of your current Windows, but before, make sure to check the hash of your iso to avoid a corrupted win.
once done, mount the iso with daemontool or with windows explorer.
To repair the image of Windows 10 by specifying as source the installation file located in the ISO
Either you have an install.wim file so:
Quote Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:X:\sources\install.wim:N /LimitAccess
Or you have an install.esd file:
Quote Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:X:\sources\install.esd:N /LimitAccess
Replace X by the drive letter associated with the ISO image and N by the index of the Windows 10 edition to be repaired.
Detail of indexes and editions of Windows 10
The install.wim/install.esd file may contain several editions of Windows 10, identified by indexes:
Quote index 1: Windows 10 Home ;
index 2 : Windows 10 Home N ;
index 4 : Windows 10 Education ;
index 6 : Windows 10 Professional...

You can find all the available indexes in the file install.wim/install.esd with the command :
Quote DISM /Get-WimInfo /WimFile:install.(wim|esd)
To get more information about an index :
Quote DISM /Get-WimInfo /WimFile:install.(wim|esd) /Index:1
Now run the command again
Quote sfc /scannow
the System File Checker tool should successfully run and repair any errors.
