Part 1. What is EFI partition?

The EFI (Extensible Firmware Interface) partition is a special partition that manages the computer's boot process and stores the information necessary to start the operating system.

EFI partition contains the boot loader and system files and plays an important role when starting your computer.

Part 2. Why do I need to move EFI partition?

The EFI partition has a capacity of 99MB, and 200MB or more of free space is required to install macOS. When you try to extend an EFI partition using the Windows 10 Disk Management tool, the "Extend Volume" button is disabled and the operation is not possible. Therefore, it is necessary to resize EFI partition.

Part 3. What is the size of EFI partition in Windows?

Windows EFI partitions typically have a capacity of about 100MB to 300MB.

This partition stores the boot loader and system files and works effectively despite its small size.
