hi I'm attempting to image a machine, but after following the instuctions listed on http://technet.microsoft.com/en-us/library/ee523217(v=ws.10).aspx I have hit a problem. The reference computer requires drivers to access the local HDD's. Does anyone know how I can add my drivers to the WinPE bootable Flash Drive?
You'll need to mount the actual WIM to add drivers.
Dism /Mount-Wim /WimFile:C:\test\images\Your.wim /MountDir:C:\test\offline
Once your WIM is mounted, you can add drivers with Dism. I usually have a whole subdirectory worth of drivers, which you can add all at once.
Dism /Image:C:\test\offline /Add-Driver /Driver:c:\drivers /Recurse /ForceUnsigned
Then you need to save the changes...
Dism /Unmount-Wim /MountDir:C:\test\offline /Commit
...and copy the new WIM to the flash drive (which you've apparently done before, based on your link). For more information, there's a TechNet article.
