Creating a ConfigMgr (SCCM) Bootable Media – PowerShell Style

Here is a PowerShell script that will create Bootable Media for ConfigMgr. In this example, I generate an ISO file and add a prestart command / package (to launch the TSBackground solution from Johan Schrewelius).

Note: If you are running into limitations with the New-CMBootableMedia cmdlet, like specifying a CMG MP, you can also use the createmedia.exe tool that comes with ConfigMgr, and that the console is using behind the scenes. It has many more options, and is documented here: https://learn.microsoft.com/en-us/intune/configmgr/develop/reference/osd/operating-system-deployment-createmedia.exe
