Windows 10: How to use unallocated space when extend volume is greyed out?

I have been running a dual boot system Win10 / Win11 for a while now originally Win10, then dual boot to Win11 created on a new partition. I no longer use the Win10 partition enough to justify it. Information online was to use Disk Manager to delete the Win10 partition then extend the Win11 volume to use the unallocated space. I deleted the Win10 volume, and now the order of my partitions is: 500MB EFI System - 298GB Unallocated - Windows 11 655GB Boot, Page File... - 787MB Recovery I tried uploading a screenshot, but I kept getting an File Failed to Upload error. However, now when I right

Extending volume problems

Looks like you'll need to go dynamic.

 

extend c drive storage space

Hi, I'm , an Independent Advisor.

Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

- Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

- The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

#1. Increase C Drive Space with Adjacent Unallocated Space

Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

Step 3. Set and add more space to your system C drive and click "Next" to continue.

Step 4. Click "Finish" to complete the process.

Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

Hope this helps. Let me know if I can help you further!

 

Unable to Use Unallocated Space to Extend Partition

Okay...thanks. Will look at it tomorrow. FYI, I figured out how to get that unformatted G partition back into D.

In Disk Management, I right clicked G and selected "Delete Volume." That rendered the partition as unallocated. I was then able to extend D with that space.

Thanks again for all of the help!
