Resolution

Update the WinPE Image to Support VB Scripting

1. Create a folder on the root of the C drive named WinPE. 
   C:\WinPE
   
   
2. Open a cmd with Administrator privileges
   Execute the following command to mount the WinPE image in the new folder
   
   imagex /MOUNTRW "C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\en-us\winpe.wim" 1 c:\WinPE
   
   Remarks : imagex.exe is in this directory C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\DISM
   
   
   
   
   

3. Run the following command to add the WinPE VB scripting package

   dism /image:c:\Winpe /add-package /packagepath:"C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\WinPE_OCs\winpe-scripting.cab"
   
   
   
   
   

4. Execute the following command to confirm that the packages have been installed to the WINPE image: 

   dism /image:c:\Winpe /get-packages
   
   
   
   

5. Execute the following command to commit the changes made to the WINPE image:

   imagex /unmount c:\Winpe /commit
   
   
   
   

6. The file C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment\amd64\en-us\winpe.wim is updated
   
   
   
   
7. If you have created the boot image, run the Boot Image Update wizard in the DSM explorer to update the WinPE boot image for use in OSIM. If you have not created the boot image, run the New Boot Image wizard. If you have created the boot image, run the Boot Image Update wizard in the DSM explorer to update the WinPE boot image for use in OSIM. If you have not created the boot image, run the New Boot Image wizard. 
   
   

Add Scripts and Supporting Files to the WinPE Image

After the update to the WinPE image to support VB scripting is complete, add the scripts and supporting files to the image.
Follow these steps:

1. Download the 5 attached files : DiskPercent.vbs, Diskpart_template_legacy.txt, Diskpart_template_uefi.txt, Movecd.txt and DelandCreate.txt
   
   DiskPercent.vbs splits the disk 0 in 2 partitions (letter C and D) with a size of 50% each. If another repartition is needed, line 45 could be changed :
   
   Example for 60% on C and 40% on D :
   DISKUSE=60
   
   
2. Copy these 5 files to the following location: 
   C:\Program Files (x86)\CA\DSM\osimips\os-template\updates\winpe10x64\amd64\ca-osim
   
   
3. Update the OSIMRUN.CMD file, which is the script that is invoked when WinPE is booted. This script is located in the same folder as the copied files in step 2. 
   
   Update this part
   

   :UseWinPEPartition
   x:\amd64\ca-osim\sdmpcimg -m TFTP -t #MPCPATH#/camenu/%$WinPEPartition$%
   diskpart /s %$WinPEPartition$%
   if %ERRORLEVEL% NEQ 0 (
       diskpart /s x:\amd64\ca-osim\osimdisk_remove_letterC.txt
       diskpart /s %$WinPEPartition$%
   )

   by this part (2 lines put in comment and 1 added line) :
   

   :UseWinPEPartition
   REM x:\amd64\ca-osim\sdmpcimg -m TFTP -t #MPCPATH#/camenu/%$WinPEPartition$%
   REM diskpart /s %$WinPEPartition$%
   cscript.exe x:\amd64\ca-osim\DiskPercent.vbs %$WinPEPartition$%
   if %ERRORLEVEL% NEQ 0 (
       diskpart /s x:\amd64\ca-osim\osimdisk_remove_letterC.txt
       diskpart /s %$WinPEPartition$%
   )

   
   
   
   
   
4. Save the file
   
   
5. Create your WinPE boot image. If you have created a WinPE boot image and registered the image in CA Client Automation, run the Update Boot Image wizard in DSM Explorer to update with the customizations. 
   
   
6. In OSIM job, select a WinPEPartition value :
   
   Use special partition file WIN11.wp1 for Legacy BIOS from CAMENU
   or
   Use special partition file WIN11.wp2 for UEFI from CAMENU
   
   
   
   Diskpart_template_legacy.txt template file is used for Legacy BIOS option
   Diskpart_template_uefi.txt template file is used for UEFI option
