Not sure I understood your question.
That was my situation: I couldn't log to the safe mode with command prompt because it didn't find any administrators (but I had two administrators working in normal conditions: the one with my MS account and the hidden administrator; this last one wasn't hidden because I activated it).
More information: some weeks/months ago I removed all the administrators, but I can't remember how I fixed it.
Then some days ago I found I couldn't log in at all when trying to use the safe mode with command prompt.
Why I had to go to safe mode with command prompt?
Because I found
I couldn't log in to new windows accounts.
I could create new accounts through the windows GUI, but, when I tried to log in to the new created account, I always (i.e., with each new account) received the message
The user profile service service failed the sign-in. User profile cannot be loaded..
Then, I tried to fix this last problem with:
- tweaking.com windows repair "Repair reparse points": it didn't fix it (but it fixed my reparse points and junctions).
- chkdsk (on all partitions): it didn't fix it (but it adjusted few errors in my partitions)
- substitute the c:\users\default folder with one present in a system image I've done with paragon B&R16 in September 2016 (after the W10 anniversary update, most likely): this fixed it, finally (and luckily).
Indeed I remembered I likely removed some empty folders in the c:\users\default folder (and not only there), thinking they weren't necessary (but, in fact, they are necessary...:banghead:).
It also seems now I'm able to run successfully the
perfmon /report. :rofl12:
