Creating a Customer-Supplied Windows Operating System Image

The Customer-Supplied OS Toolkit for Windows requires:

A Microsoft Windows image (.wim) file as a source file
Microsoft Windows image files are available on Windows operating system installation media that you obtain from your operating system vendor (for example, a DVD), or a custom .wim file that you previously created.
Note: To learn more about .wim files and creating them, refer to documentation available from the Microsoft Windows website.
Administrative credentials to a workstation with the following:
- Windows 7, Windows Server 2008 R2, or later (32-bit or x64-bit).
- Windows PowerShell 4.0 or higher.
- Disk space of at least 2.5 times the size of the source .wim file.
  For example, if your .wim file is 8 GB, be sure you have 20 GB available disk space.

Obtaining and Launching the Toolkit

Access the Fabric Management Platform, locate the /Unisys/Tools/ directory, and then download the Customer-Supplied OS Toolkit for Windows to your local workstation.
Unzip the toolkit package to your preferred location on your workstation.
Launch a Command Prompt window with administrative privileges.
Change the directory to where you unzipped the toolkit package.
Execute the following command:
```
powershell –executionpolicy bypass –File .\Windows-CSO-Tookit.<version>.ps1
```
Where <version> is the version number in the filename.

Using the Toolkit to Create Images

To create an operating system image, launch the Customer-Supplied OS Toolkit for Windows, and do the following:

In the Select Source WIM File field, browse to your desired Microsoft Windows image (.wim) file.
In the Select OS Image field, select your desired operating system from the drop-down list.
Note: If your source .wim file is the Microsoft install.wim file, only the operating systems supported for the release are listed.
In the Select Target Folder field, browse to the location where you want to store the operating system image you are creating and its corresponding blueprint.
In the Image Name field, if you do not wish to use the default name, type in a name for your image. The filenames for the image and corresponding blueprint will contain the text in this field, as well as automatically generated version information (for example, date and toolkit version number).
Note: Do not use spaces in the filename.
In the Image Description field, fill in a short description.
Note: This description is displayed on the Fabric Manager user interface, and must be less than 32 characters.
When all the required information is entered, click Build Images. Depending on your image size, the process can take 30 minutes or longer.
When the process completes, a status dialog box appears.
Click OK.
If desired, click View Log to review the build log file in Notepad.
Click Exit to quit the utility.

The resulting operating system image and its corresponding blueprint are stored at the location you specified. Use the Fabric Manager user interface to add the operating system image and its corresponding two blueprint images to the desired platform. For more information, see Uploading Customer-Supplied Operating System Images to Fabric Manager.

Note: Be aware that there is limited storage for images on each partitionable enterprise partition platform (PEPP).
