如何在GPT格式下创建EFI和MSR分区

回答1:

方式一,使用diskgenis工具:
选中系统盘右键删除磁盘,点击左上角的保存更改,这步操作比较狠,直接磁盘都删除了,一定要记得备份重要数据。接着来给磁盘创建新分区,右键新建分区,在弹出选项框新建分区时注意勾选esp(efi)和msr两个选项,确定便可。
方式二,用系统自带的diskpart创建efi和msr分区,也就这步稍微麻烦一点,操作方式如下
1.运行-cmd调出命令提示符,输入“diskpart”命令
2.输入“list
disk”命令列出当前计算机上的所有物理磁盘
3.输入“select
disk
x”命令选择你要操作的物理磁盘,其中“x"代表磁盘编号。
4.输入”create
partition
efi
size=n”创建efi分区,其中“n”是以m为计数单位的空间大小,我分了100m,直接=100就行。
5.输入“create
partition
msr
size=n
”创建msr分区,其中“n”是以m为计数单位的空间大小,我分了128m,直接=128就好。

回答2:

仅当使用UEFI模式以及GPT分区表的时候需要EFI系统分区(又称ESP),对于GPT分区表,EFI分区是必需的,它用来存放操作系统的引导器(loader),而MSR不是必需的,仅当使用Windows系统时才需要MSR保留分区
MSR分区即
Microsoft
保留
(MSR)
分区。是每个
GUID
分区表
(GPI)
磁盘都要求的分区。
  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。
