  • Now, Type ‘diskpart’ without quotes and hit the ‘Enter’ key.
  • Type the following commands one after the other:

    • list volume: (this list all volumes on disk 0 is listed.)
    • select volume n: (the n implies the number of system partition.)
    • active: (this indicates the active system partition.)
  • From the list of the displayed system partition, determine the right partition which should be active.
