MSR: Microsoft Reserved Partition
Understanding the MSR
The Microsoft Reserved Partition (MSR) is a small, 16 MB partition created on each GPT drive. Its purpose is to aid in partitioning, and it contains the Partition GUID. No significant data is stored within the MSR, but chunks may be taken from it to create new partitions.
MSR and EFI Partitions
MSR and EFI (Extensible Firmware Interface) partitions are only supported on GPT (GUID Partition Table) disks. They are typically created during the installation of an operating system.
MSR and the Operating System
The MSR reserves space on each disk drive for subsequent use by the operating system. This space can be used for various purposes, such as storing boot configuration data or system recovery information.
Importance of GPT Reserved and EFI System Partitions
GPT reserved and EFI system partitions are essential for the proper functioning of GPT disks. They facilitate the booting process and provide a dedicated space for storing system configuration data.
Creating MSR and EFI Partitions
To create an MSR and EFI partition, follow these steps: 1. Create a partition with a size of 100 MB and format it as FAT32. 2. Label the partition as "EFI System Partition". 3. Create another partition with a size of 16 MB and format it as FAT32. 4. Label this partition as "Microsoft Reserved Partition".
Conclusion
MSR and EFI partitions are crucial components of GPT disks. They facilitate partitioning, provide space for storing system configuration data, and contribute to the overall stability and functionality of the operating system. Understanding their purpose and creating them properly is essential for ensuring optimal system performance.
