When you try to extend the C drive from the Disk Manager tool but the Extend volume greys out, the recovery partition prevents the C drive from extending the volume.
Today, I will show you how to solve it.
1. Mount the Windows Server 2022 (2019) ISO image file.
2. Open the Command Prompt as administrator.
3. Type diskpart and press the Enter key.
4. Type list disk and press the Enter key.
5. Type select disk 0 and press the Enter key.
6. Type list partition and press the Enter key.
7. Type Select Partition 4 and press the Enter key.
8. Type delete partition override and press the Enter key.
9. Type exit to leave DiskPart and press the Enter key.
10. Type the below command to mount the deployment image and management tool, and press the Enter key.
DISM /MOUNT-Image /IMAGEFIle:E:\Sources\Install.wim /index:1 /mountdir:c:\Temp /Readonly /optimize
Note:
You need to create the Temp folder manually.
11. Type the below command to Robocioy the Recovery data.
Robocopy /MIR c:\Temp\Windows\System32\Recovery\ c:\Windows\System32\Recovery
12. Type the below command to reset the recovery image.
reagentc /setreimage /path c:\windows\system32\recovery
13. Type the below command to unmount the deployment image and management tool.
