在开始安装之前,我使用diskpart来检查哪个驱动器是C:驱动器。Diskpart说C:驱动器是磁盘2。但是,在Windows安装中,该驱动器现在是“驱动器6”。
这很简单,因为您试图将Windows枚举的磁盘列表与BIOS / UEFI枚举的磁盘列表进行比较。
The BIOS may or may not enumerate disks in a specific order. There is no direct relationship between the BIOS order, and the order in which Windows numbers the disks.
After Windows takes control the following applies.
During startup, Windows switches from using the BIOS INT13 support to native Windows drivers to access disks. Windows waits for several seconds for the system disk to enumerate through Plug and Play. When there is a match within the time-out period, normal startup will proceed.
Windows在启动期间切换到本机Windows存储控制器驱动程序后分配的磁盘号仅取决于即插即用枚举和处理磁盘的顺序。Windows将枚举可用的固定磁盘,然后枚举可移动磁盘,前提是假定系统中已经存在并安装了正确的本机Windows驱动程序。
我该如何事先检查?
您可以检查固件设置以确定顺序,因为WinPE(Windows预安装环境)磁盘枚举将基于BIOS / UEFI提供的顺序而不是安装过程中磁盘选择阶段的Windows启动方法。
