MDT补丁 MDT_KB4564442 MDT FAILURE ( 5616 ): 15250: Verify BCDBootEx

这个补丁说是错误识别BIOS为UEFI模式。

结果导致分区步骤变为了GPT格式，MBR分区格式，无法激活什么的。

1. Close the Deployment Workbench.

2. Backup the existing x86 and x64 versions of the Microsoft.BDD.Utility.dll file in the following locations.
   %ProgramFiles%Microsoft Deployment ToolkitTemplatesDistributionToolsx86
   %ProgramFiles%Microsoft Deployment ToolkitTemplatesDistributionToolsx64

3. Copy the new files extracted from MDT_KB4564442.exe over the old versions.

4. For each deployment share that you have created, repeat the file replacement (e.g. C:DeploymentShareToolsx86, C:DeploymentShareToolsx64, etc.).

5. Open the Deployment Workbench, select the Deployment Share and choose the Update Deployment Share option, choosing to completely regenerate the boot image.  Perform this step for each deployment share to ensure each one is updated with the correct binaries.

就是替换这两个文件，重新升级一下部署，重新生成PE，替换一下。

主要替换共享目录里面的。

1. For each deployment share that you have created, repeat the file replacement (e.g. C:DeploymentShareToolsx86, C:DeploymentShareToolsx64, etc.).

然后重新生成PE镜像。
