I've tried everything, including running bootrec numerous times and I can't boot into Windows10. It started when I came home and noticed Windows was informing me I was missing my boot master. Everything was working wonderfully yesterday, what happened I have not a clue. Using Windows10 installation disc I was able to see my Windows Drive and all my folders were there, as well, I was able to preform a bootrec /mbr - successfully; bootrec /fixboot - successfully, when running bootrec /rebuildbcd the Windows installation is found but when I agree to add the installation to the boot list, I get an error; the reqested system device cannot be found.
I've looked up almost every error message and tried everything I've searched for and no solution and a re-install is not in the question. I know it's possible to get it to boot back to normal I just have not a clue.
