Import-OSMedia

Since you are going to be working mounting WIM files, make sure you open PowerShell with Admin Rights (Elevated)

You can either insert a Windows DVD or mount an ISO. Once this is done, you can import the Operating System. In PowerShell, simply use the following command

Import-OSMedia

OSDBuilder will scan the drives for an Operating System to import and display the results in GridView. Simply select the Operating System you want to import and press OK

You can select multiple Editions from multiple ISO's at the same time

The Operating System Index that was selected will be mounted

Mounted Inventory

Once mounted, a full inventory will be saved, and the Operating System will be copied into OSDBuilder\OSImport. This will take between 5-10 minutes to complete per Operating System Index that was selected
