(FIX) Extend Volume Option Greyed Out In Windows 10/11 | Extend C Drive

Introduction

This tutorial will guide you through the process of fixing the "Extend Volume" option being greyed out in Windows 10 and 11, particularly when trying to extend the C drive. This issue often arises due to the presence of recovery partitions or unallocated space not being in the correct location. We'll explore effective methods to resolve this issue, ensuring you can successfully extend your C drive.

Step 1: Delete Unnecessary Volume Partitions

To extend your C drive, you may need to delete any unnecessary volume partitions that are adjacent to it. Follow these steps:

1. Open Disk Management:

   • Right-click on the Start menu and select "Disk Management."

2. Identify the New Volume:

   • Look for any volume that is not being used (typically labeled as "New Volume").

3. Delete the Volume:

   • Right-click on the unnecessary volume.
   • Select "Delete Volume" and confirm the action. This will convert the space into unallocated space.

Step 2: Delete Recovery Partition Using Command Prompt

If the "Extend Volume" option is still greyed out, you may need to delete the recovery partition. Use these steps carefully, as this will remove the recovery option:

1. Open Command Prompt as Administrator:

   • Press Windows + X and select "Windows Terminal (Admin)" or "Command Prompt (Admin)."

2. Launch Diskpart:

   • Type the following command and press Enter:

     diskpart
     

3. List Disks:

   • Enter the command:

     list disk
     

   • Identify your main disk (usually Disk 0).

4. Select the Disk:

   • Type the command, replacing 0 with your disk number:

     select disk 0
     

5. List Partitions:

   • Enter:

     list partition
     

6. Select the Recovery Partition:

   • Identify the recovery partition (usually small in size) and select it:

     select partition X
     

   • Replace X with the number of the recovery partition.

7. Delete the Recovery Partition:

   • Type the command below to delete the partition:

     delete partition
     

Step 3: Extend the C Drive

Once you have unallocated space available, you can now extend your C drive:

1. Return to Disk Management:

   • If you have closed it, open Disk Management again.

2. Right-click on C Drive:

   • Select the C drive (usually labeled as "C:") and right-click it.

3. Choose Extend Volume:

   • Click on "Extend Volume" and follow the wizard to utilize the unallocated space.

4. Complete the Process:

   • Confirm your selections and allow Windows to extend the C drive.
