Steps mounting windows from install DVD:


1) Create a folder to mount a Windows Imaging File (WIM) in with the command  mkdir c:\mountdir


2) Determine the index number for a Server with a GUI image (for example,  SERVERDATACENTER, not SERVERDATACENTERCORE) using this command at an elevated command prompt: Dism /get-wiminfo /wimfile:<drive>:sources\install.wim


3) Mount the WIM file using this command at an elevated command prompt:  Dism /mount-wim /WimFile:<drive>:\sources\install.wim /Index:<#_from_step_2> /MountDir:c:\mountdir /readonly


Start Windows PowerShell and run this cmdlet:


4) Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell –Restart –Source c:\mountdir\windows\winsxs


5) Alternatively, if you want to use Windows Update as the source instead of a WIM file, use this Windows PowerShell cmdlet:


Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell –Restart
