When running this command X would be the drive letter to your setup media
DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:\Sources\Install.wim:1 /LimitAccess
Your setup should be in the USB port and you need to change X to that port drive letter..
Also if you need to verify the there is an install.wim inside the \sources folder on the setup media, as it may have an install.esd
which then you would need to change the command to
DISM /Online /Cleanup-Image /RestoreHealth /source:ESD:E:\Sources\Install.esd:1 /LimitAccess
I changed the X to E as I assume you have C=OS and D=cd/dvd - either way change E X to the drive letter of your setup media
