Windows Server 2016 – Extend C: Drive Without Third-Party Tools (EFI Partition Between C: and Unallocated Space)

Hii,

In this case, I wouldn’t recommend using the method to recreate the EFI partition, as your Windows might fail to boot.

If you need to increase EFI space to update, try the procedure below:

Search for cmd. Press-and-hold or right-click on Command Prompt in the results, and select Run as administrator.

At the command prompt, type mountvol y: /s and then hit Enter. This will add the Y: drive letter to access the System Partition.

Switch to the Y drive by typing Y: and press Enter. Then, navigate to the Fonts folder by typing cd EFI\Microsoft\Boot\Fonts. Once there, type del . to delete font files. The system may ask you if you are sure to continue, press Y and then Enter to continue.
