What is the meaning of ESP partition and MSR partition in Disk Genius fast partition?

In Disk Genius fast partition, what do the first two ESP partitions and MSR partition mean?

XNUMX. ESP is the EFI system partition

1) Full name EFI system partition (abbreviated as ESP):

• The MSR partition itself does nothing, it is a veritable reserved partition.
• Although ESP is a FAT16 or FAT32 formatted physical partition, its partition identifier is EF. (hex) is not the regular 0E or 0C.
• Therefore, this partition is usually invisible under Windows OS.

2) ESP is an OS independent partition:

• After booting the OS, it no longer depends on it.
• This makes ESP suitable for storage system-level maintenance tools and data.
• (eg: boot managers, drivers, system maintenance tools, system backups, etc.) and even ideal for installing special operating systems in the ESP.

3) ESP can also be seen as a safe hidden partition:

• Boot management programs, system maintenance tools, system recovery tools and images can be put into the ESP to create a "one-click recovery system".
• In addition, not only can DIY be done by yourself, but it is also more convenient and versatile.

Second, the MSR partition is a reserved partition

1) Windows will not create a file system or write data to the MSR partition

• MSR partitions are partitions reserved for adjusting the partition structure.
• In Windows 8 and above system updates, the MSR partition will be detected.
• MSR partitions are essentially "unallocated space" written on the partition table.
• Microsoft's purpose is not to want others to take action.

2) MSR partitions are used to prevent GPT disks from connecting to legacy systems:

• Avoid being seen as an empty unformatted hard drive by the old system and continuing to run (eg, reformat), resulting in data loss.
• With this partition on the GPT disk, if it is connected to an older system (such as XP), it will be prompted as an unrecognized disk, and the next step cannot be performed.
