Use a partitioning tool: DiskGenius
All hard disks will be displayed on the left side of the list (if not displayed, please check the compatible hard disk type of the device), right-click GPT to select new hard disk, and select New Partition (you can check to create ESP and MSR partitions at the same time).
Note 1: MSR partition (Microsoft Reserved Partition) is a partition on a GPT disk used to reserve space for backup. For example, this space is used when converting a disk to dynamic.
Note 2: The ESP partition (UFFI system partition) is used for computer systems that use UFFI BIOS to start the operating system. The boot management program, drivers, system maintenance tools, etc. are stored in the partition.
Note 3: If the computer uses the UFFI system, or may use the current disk to start the system on the UFFI system in the future, you need to create an ESP partition.
Suggest a new partition, this step is checked by default, click OK. At this time the hard disk has not been formatted, click the upper left corner to save the modification, click Yes in the pop-up window, you can use the new disk.
