Windows Server 2022 – How to Extend C: Partition

windowswindows-server-2022

I'm trying to extend my C: partition (I have 10 GB Unallocated), but the extend option is grayed out :

Disk Image

Same results with diskpart command : There is not enough usable free space on specified disk(s) to extend the volume.

And the extend failed with the File and Storage Services (Server Manager\File and Storage Services\Volumes\Disks) :

File and Storage Services Image

Any idea about this issue ?

Many thanks !

The extent must be contiguous.

You may be able to use a partition tool like GParted to move the recovery partition to where it should be, at the beginning of the disk.
