When running offline from installation media you might need to specify a source ESD or WIM file to repair from

DISM /Image:{:DriveLetter:}: /WinDir:{:WindowsFolder:} /Cleanup-image /RestoreHealth /Source:WIM:{:InstallMediaDriveLetter:}:\sources\install.wim:{:ImageIndex:}

DISM /Image:{:DriveLetter:}: /WinDir:{:WindowsFolder:} /Cleanup-image /RestoreHealth /Source:ESD:{:InstallMediaDriveLetter:}:\sources\install.esd:{:ImageIndex:}

To identify which index you want from the source WIM/ESD run the following

DISM /Get-ImageInfo /ImageFile:{:SourceFilePath:}

You can mount the image index to a folder

DISM /Mount-Image /ImageFile:{:SourceFilePath:} /Index:{:ImageIndex:} /MountDir:{:MountDirectory:} /ReadOnly
