一、用处:
1、MSR分区即 Microsoft 保留 (MSR) 分区每 GUID 分区表 (GPI) 磁盘都要求分区 系统组件。
X
2、WIN8系统安装版分区时,系统自动划分出“分区1、2、3
3、其中300MB为恢复区,100MB为Efi分区,128MB为MSR分区
4、很多人用GHOST系统的时候,用diskgen分区老是出现用Disk Genius来分区老是出现ESP区和MSR分区,然后就安装不了系统了。
二、关于msr分区的主要错误理解:
1.把预留的msr分区删了的3T磁盘就自动变成2T+800G两个盘了,不能分成一个一个硬盘一个区了。
2.msr分区是UEFI启动的必要条件,删掉之后系统无法启动。
3.msr分区不可以删除,是GPT必需的,删除以后容易丢失数据。
4.存在msr分区的系统不能用OEM激活,只能正版。

MSR分区到底有什么功能 .综合讨论区[引用时间2017-12-29]
esp就是efi系统分区,用于保存系统引导文件;
msr是微软保留分区, GPT格式磁盘用于安装Win7/8系统都会自动创建该分区。
EFI系统分区,即 EFI system partition,简写为
ESP。ESP 是一个 FAT16 或 FAT32 格式的物理分区,但是其分区标识是 EF (十六进制) 而非常规的 0E 或
0C,因此,该分区在 Windows 操作系统下一般是不可见的。支持 EFI 模式的电脑需要从 ESP 启动系统,EFI 固件可从 ESP 加载
EFI 启动程序或者应用。
MSR分区(Microsoft Reserved Partition,缩写MSR)即Microsoft 保留 (MSR) 分区。是每个 在GUID 分区表 (GPT) 上的 Windows操作系统(windows7以上)都要求的分区。
系统组件可以将 MSR 分区的部分分配到新的分区以供它们使用。例如,将基本 GPT 磁盘转换为动态磁盘后,系统分配的 MSR 分区将被用作“逻辑磁盘管理器”(LDM) 元数据分区。
MSR 分区的大小会因 GPT 磁盘的大小不同而发生变化。对于小于 16 GB 的磁盘,MSR 分区为 32 MB。对于大于 16 GB 的磁盘,MSR 分区为 128 MB。MSR 分区在“磁盘管理”中不可见,用户也无法在 MSR 分区上存储或删除数据。
