FIX: DISM Error 50, DISM does not support servicing Windows PE with the /Online option (Solved)
This tutorial contains instructions to resolve the following error when running the DISM command "Dism.exe /Online /Cleanup-Image /Restorehealth" from the Windows Recovery Environment: "Error 50, DISM does not support servicing Windows PE with the /Online option".
The above error is occurred, because in WinRE the operating system is not running, so the /Online switch is useless at this case. In fact the /Online switch in DISM tool, specifies that the action is to be taken on the operating system that is currently running.
How to fix: Error 50 DISM does not support servicing Windows PE with the /Online option.
1. Inside the WinRE command prompt window, get a list of all available drives, by giving this command:
- wmic logicaldisk get name
2. Then find out which drive contains the "Windows" folder, by typing this command: *
- dir drive-letter:
* e.g. To see the contents of the C: drive, type: "dir C:" (without quotes). If you cannot see the "Windows" folder on the C: drive, then continue to the next drive (e.g. "dir D:", "dir E:", etc.), until see the "Windows" folder.
[As you can see at the screenshot below, the Windows folder (at this case) is located at the D: drive.]
3. Once you find the "Windows" drive (e.g. the "D" in this example), give this command to repair the offline Windows image:
- dism.exe /Image:D:\ /Cleanup-Image /Restorehealth
* Note: Where D = the Windows drive. (Change it according your situation)
4. When the DISM operation is completed, give the following SFC command to complete the repairs. *
- SFC /SCANNOW /OFFBOOTDIR=D:\ /OFFWINDIR=D:\Windows
* Note: Where D = the Windows drive. (Change it according your situation)
5. When the operation is completed, reboot your computer.

Thank you, thank you, thank you! So many DISM instructions assume you are using it from within windows, this was the first tutorial I found telling me what to do from the repair environment. After following the instructions, I rebooted but still got the RE, so thought it hadn't worked (even though it told me it had repaired files) so I tried a system restore which also failed. Rebooted after that and all came up good. Not sure quite what was going on, but certain it was thanks to you.
