OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.
