Win 8 won't start after running Norton Utilities Disk Dr

Ran Norton Disk Doctor now Windows won’t start. See video: https://www.dropbox.com/s/ps44spfzynewemc/IMG_0354.MOV

What file does this Norton program change to make it boot to Disk Doctor instead of the normal windows boot cycle?

I have access to files through command prompt/Notepad… I can edit the affected file or possibly replace it with a backup…

I prefer to fix the specific problem as opposed to doing a file and application disrupting repair through Windows.
