Protect end users from accidentally modifying utility partitions by identifying them using a GPT attribute.

The MSR is a reserved partition that does not receive a partition ID. In WindowsВ 10, the size of the MSR is 16 MB.ДЄdd an MSR to each GPT drive to help with partition management. 512 bytes x 65527 = 32 MB, which is less than the 100 MB minimum size for this partition. The minimum partition size of FAT32 drives is calculated as sector size (4KB) x 65527 = 256 MB.ДЄdvanced Format 512e drives are not affected by this limitation, because their emulated sector size is 512 bytes.

This partition is managed by the operating system, and should not contain any other files, including Windows RE tools.ДЇor Advanced Format 4K Native drives (4-KB-per-sector) drives, the minimum size is 260 MB, due to a limitation of the FAT32 file format. The minimum size of this partition is 100 MB, and must be formatted using the FAT32 file format. This partition is usually stored on the primary hard drive. On GPT drives, this is known as the EFI System Partition, or the ESP. The device must contain a system partition. Additional drives may use either the GPT or the master boot record (MBR) file format.ДЄ GPT drive may have up to 128 partitions.Д®ach partition can have a maximum of 18 exabytes (~18.8 million terabytes) of space.

When you deploy Windows to a UEFI-based device, you must format the hard drive that includes the Windows partition by using a GUID partition table (GPT) file system.
