Having trouble fixing the “Extend Volume” option that’s greyed out on your computer? It can be frustrating when you cannot extend your disk space, but don’t worry, solutions are available. There may be many reasons for the “extend volume grey out” error, and we need to know about them. Firstly, it is important to understand why this happens and how we solve it so that you can work on your computer smoothly again. Sometimes, it’s due to certain limitations or issues with your disk partitions. Before delving into the practical steps, explore why such errors occur. Understanding these reasons sheds light on the significance of disk conversion and equips users with the knowledge to navigate potential pitfalls effectively.
Part 1: Why Does Extend Volume Greyed Out?
When the “Extend Volume” option appears greyed out in Disk Management, it typically indicates certain conditions or limitations preventing volume extension. Despite having unallocated space on your disk, various factors can contribute to this error. Some of them are as follows:
- Unallocated Space: The disk you are trying to extend may not have an unallocated space next to it. Unallocated space is necessary for extending a volume.
- File System Limitations: Some file systems, like FAT32, might only support extending volumes with additional tools or conversions.
- System Partition Restrictions: You cannot extend the system partition (where your operating system is installed) while the operating system is running.
- Partition Type: Some partitions, like OEM or recovery, may not be extendable due to their specific purposes.
- Dynamic Disk Conversion: If the disk is dynamic, you may need to convert it back to a basic disk to extend volumes, which might involve data loss.
- Unsupported File Systems: Certain file systems or disk configurations may not support volume extension through the built-in Windows Disk Management tool.
Part 2: How to Fix Extend Volume Greyed Out Easily?

Way 2: Convert to NTFS and extend the volume
When it comes to managing disk partitions in Windows 10 and other operating systems, Disk Management stands out as a native tool offering convenience and efficiency. Apart from its primary functions, Disk Management can also facilitate the conversion of FAT32 to NTFS file systems and extend volumes for optimized storage utilization. Here’s a comprehensive guide on how to accomplish these tasks seamlessly.
Before proceeding with the conversion, it’s crucial to note that formatting a partition to change its file system will result in data loss. Therefore, ensure you have backed up all essential data beforehand.
Step 1: Access Disk Management
- Press “Windows + R” to open the Run dialog box.
- Type “diskmgmt. msc” and hit Enter to launch Disk Management.
Step 2: Format the Partition
- In Disk Management, locate the partition you wish to convert from FAT32 to NTFS.
- Right-click on the partition and select “Format” from the context menu.
- In the Format dialog box, provide a volume label for the partition.
- From the “File system” dropdown menu, choose “NTFS.”
- Ensure that the “Perform a quick format” option is selected by default.
- Click “OK” to initiate the formatting process.
Step 3: Extend Volume
After converting the file system to NTFS, consider extending the volume to accommodate additional data or optimize disk space usage.
- Utilize Disk Management to access the newly converted NTFS partition.
- Right-click on the NTFS partition and select “Extend Volume.”
- Follow the Extend Volume Wizard prompts to add unallocated space to the partition.
Way 3: Create Adjacent Unallocated Space
Do you need to extend your C drive due to the absence of adjacent unallocated space? The C drive extended volume can be enabled by deleting partitions or shrinking existing ones. With this article, you will walk through the steps to create adjacent unallocated space, allowing you to extend your C drive effortlessly.
Step 1: Delete Unnecessary Partitions
- Open Disk Management by right-clicking the Windows icon and selecting “Disk Management” or pressing Windows + R, typing “diskmgmt. msc,” and hitting Enter.
- Identify any empty partitions next to your C drive.
- Right-click on these partitions and choose “Delete Volume” to free up space. Confirm the deletion if prompted.
Step 2: Shrink Existing Partitions
- Find a neighboring partition with enough free space if there are no empty partitions.
- Right-click on this partition and select “Shrink Volume.”
- Specify the amount of space you want to shrink the partition by and click “Shrink” to create unallocated space.
Step 3: Extend C Drive
- Once you have adjacent unallocated space, right-click on your C drive partition.
- Choose “Extend Volume” and follow the wizard to add the unallocated space to your C drive.
- Confirm the extension; your C drive will now have more space available.
Bonus Tip: Convert MBR to GPT Partition
Converting an MBR (Master Boot Record) disk to a GPT (GUID Partition Table) disk is crucial for modernizing your storage infrastructure, especially when dealing with large drives or implementing advanced features like UEFI boot. While this process involves significant changes to the disk’s structure, it can be accomplished smoothly using the native Disk Management tool in Windows. Here’s a detailed guide on how to convert MBR to GPT partition seamlessly using Disk Management.
Preparation: Back Up Your Data
Before initiating the conversion process, it’s essential to back up or move all data stored on the MBR disk to prevent data loss during the transition.
Step 1: Delete Partitions and Volumes
- Open Disk Management by right-clicking on the Start menu and selecting “Disk Management.”
- Identify the MBR disk that you intend to convert to GPT.
- For each partition or volume on the MBR disk, right-click on it and select either “Delete Partition” or “Delete Volume.” Confirm the deletion if prompted. Ensure you have backed up any critical data, as this process will erase all content on the disk.
Step 2: Convert to GPT Disk
- After deleting all partitions and volumes on the MBR disk, right-click on the disk (not on any partition) and select “Convert to GPT Disk” from the context menu.
- A confirmation prompt will appear, informing you that converting the disk to GPT will erase all data. Confirm your action to proceed with the conversion.
Step 3: Finalization
- Once the conversion process begins, Disk Management will notify you when it’s completed.
- You may need to initialize the newly converted GPT disk and create new partitions or volumes.
Conclusion
In conclusion, troubleshooting issues like the “Extend Volume greyed out” can be frustrating but manageable with the proper knowledge and tools. By understanding the various reasons behind this error, users can navigate through potential obstacles and implement appropriate solutions. Disk Management offers versatile capabilities to address these challenges, whether it involves creating adjacent unallocated space, converting file systems, or converting MBR to GPT partitions.
