Mount-WindowsImage Issue

Question

I decided to rewrite my USB boot media to a PowerShell script. When mounting I use the following

Mount-WindowsImage -ImagePath X:\DEV.wim -Index 1 -Path "C:\windows"

The .WIM is on a separate partition on the boot USB. When called, PowerShell can't see that partition. I am guessing because I am not "working" on that disk.

Is there a way to tell that command to mount a .wim from a separate partition to the disk I am working on?

Example:

Mount-WindowsImage -DiskNumber 0 -ImagePath I:\DEV.wim -Index 1 -DiskNumber 1 -Path "C:\windows"

For adding powershell support in your WinPE boot media you need to attach some .cab files.

First you need to mount your wim and add a few packages to your boot.wim file.

The location for the optional components are as follows for x64 bit.

C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE\_OCs\

32bit optional components are located here:

C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\x86\WinPE\_OCs\

You can run this script to add the packages you need to use powershell in WinPE.

Dism /Mount-Image /ImageFile:"C:\Path\to\image\boot.wim" /Index:1 /MountDir:"C:\mount\path"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\WinPE-WMI.cab"

Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\en-us\WinPE-NetFX_en-us.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\WinPE-Scripting.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\en-us\WinPE-Scripting_en-us.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\WinPE-PowerShell.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\en-us\WinPE-PowerShell_en-us.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\WinPE-StorageWMI.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\en-us\WinPE-StorageWMI_en-us.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\WinPE-DismCmdlets.cab"
Dism /Add-Package /Image:"C:\WinPE_amd64_PS\mount" /PackagePath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\en-us\WinPE-DismCmdlets_en-us.cab"
Dism /Unmount-Image /MountDir:C:\mount\path /Commit

Then you will need to recreate your boot media:

MakeWinPEMedia /UFD C:\WinPE_amd64_PS <USBDriveLetter>:
