Hi guys, I had the same problem, you might mount a wrong image, please try to get your boot.wim information first then mount the appropriate image. imagex /info your_boot.wim_path and find which is your boot index, mine is 2, so if you situation likes mine, you should do following command: dism /mount-wim /wimfile:c:\winpe\winpe.wim /index:2 /mountdir:c:\winpe\mount hope it can help you!
