Extending a Disk by Deleting an Extra Partition

To extend your main partition, you may first need to delete the extra partition that is blocking the extension. Follow the steps below carefully.

⚠️ Warning: The delete partition override command will permanently delete the selected partition along with all its data. Make absolutely sure you select the correct partition before proceeding.


Step 1: Open Command Prompt as Administrator

  1. Press Start
  2. Type cmd
  3. Right-click Command Prompt
  4. Select Run as administrator

Step 2: Use DiskPart to Delete the Blocking Partition

In the Command Prompt window, enter the following commands one by one:

diskpart
list disk
select disk <disk_number>
list partition
select partition <partition_number>
delete partition override

Explanation:

  • list disk → Shows all available disks.
  • select disk <disk_number> → Selects the disk you want to modify.
  • list partition → Displays all partitions on the selected disk.
  • select partition <partition_number> → Selects the partition you want to delete.
  • delete partition override → Forces deletion of the selected partition.

Step 3: Extend the Main Partition

After deleting the blocking partition:

  1. Open Disk Management
  2. Right-click the main partition
  3. Select Extend Volume
  4. Follow the wizard to complete the extension

✅ Result

Once the extra partition is removed, you should be able to extend your main partition normally through Disk Management.

If you are unsure about any step, double-check the disk and partition numbers before executing the delete command.
