I’ve been using SCCM coupled with the HP Insight Control Suite to deploy our server images on bare-metal HP servers and blades. Recently, I have been working to deploy Windows Server 2008 R2. If you get the message “[Windows Package Manager] Operation failed with 0×80070002; The system cannot find the file specified”, this is caused by using an older/wrong version of a boot image. I installed the latest WAIK, re-configured the winpe.wim, imported and redistributed the new boot.wim, and finally pointed my Task Sequence to use the new boot image.
Here is a walkthrough from technet on how to update the boot image to add needed drivers and packages.
