Ignore that shopping list of repair commands you have. There's specific cases for using them, and this isn't it.
If /Apply-Image failed, it's probably a bad capture. But switching it out with a clean ISO install.wim will validate this fact. This is just to make sure your ISO environment isn't the reason why it failed.
For the image capture, was it taken on a live system by capturing the live system? That's a mistake. The original PC should be shut down, and booted from another media (like your external HDD, set up this way). This boot environment can cleanly capture all the files, since it's self-hosted and not using any of the original PC's disk files.
