As you probably know, to store files on a hard drive, it must be prepared in the right way: it must be properly initialized, partitioned and formatted. If you bought an external drive from a store, the preparation has probably already been done by the drive manufacturer. But what if you want the drive to be prepared differently? For example, you can reformat the disk or change the partitions it contains. The way to accomplish these tasks in Windows is to use the disk management program that is pre-installed with Windows.

As you can see, the system partition is protected so that even the most powerful disk management program cannot do anything with it. Note that this is not because the partition is EFI, but because the program that created the partition marked it so that other programs cannot tamper with it. But what if we want to delete the partition from the EFI system and reboot the disk from scratch?
