You could also use diskpart but I am not going to list it here. If you see a Windows folder, that is the system partition. As an example, type C: and press enter to change to C and type DIR and press enter to list the folders. *C:\Windows\WinSxS* If you are on the X drive (X:/>Source) change the partition to the Windows drive.

If nothing works, please try this procedure. Alternatively, try safemode and if you can get through, you can do a system restore. It should fix the boot and service related issues.

Boot into Windows recovery environment and run a system repair few times.
