Use DISM to Repair Windows 10 Image  

Paul Black said:

Just a quick question please.

Am I right in saying that you CANNOT use [ for example ] . . .

Code:

Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:G:\Sources\install.wim:1 /LimitAccess

. . . from a customised mounted ISO?

It's the same ISO that was used to install the customised OS!

Thanks in advance!

Hello Paul,

As long as it's a valid ISO file, you should be able to like in step 6 of option 2.

Hello @Brink,

Yes, I started off with a valid Win 10 ISO, and then customised it [ Win 10 Pro ] a LOT. I created a bootable USB and installed it. Once installed, I customised it even further with registry tweaks etc. Everything works great.

I do NOT have a problem at present. I just thought I would test out the RestoreHealth from source in case of problems in the future.

I copied the customised ISO to "R" drive, mounted it, which mounted it to "G" drive, and then ran the following cmd . . .

Code:

Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:G:\sources\install.wim:1 /LimitAccess

It gave me the following . . .

Deployment Image Servicing and Management tool
Version: 10.0.18362.1

Image Version: 10.0.18363.418

[==========================100.0%==========================]
Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243077.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

Thanks in advance.

@Paul Black,

Just to verify, did you already do step 6A or step 7A in option 2 to make sure you have the correct path and index number for the install.wim or install.esd file?

Yes, I had already performed Step 6A . . .

Code:

dism /get-wiminfo /wimfile:G:\sources\install.wim

Index : 1
Name : Windows 10 Pro
Description : Windows 10 Pro
Size : 12,599,070,866 bytes

The operation completed successfully.

Well, it appears something in the customization of the ISO is preventing it from being used as a source for DISM.

You should still be able to use an official uncustomized ISO for DISM though.

Thanks for the reply @Brink, it is appreciated.

I know that I can do that as I still have the original ISO. If I was to use that though, what impact will it have on the installed OS considering the fact that I have removed almost all of the apps, onedrive, and made over 100 reg tweaks etc etc etc?

If I was to use the original ISO as the source /RestoreHealth, would it ONLY target the OS system files etc that are installed, or will it try and ADD back those which have been removed either prior to the creation of the customised ISO, or system files that have been removed post installation?

Thanks in advance,

It should only impact system files. Apps and Registry Editor wouldn't be affected.

OK thanks.
I will create a System Image tomorrow and then use my original uncustomised ISO and give it a go!

Please let us know how it went.
