it's asking for one for her to log in.
command R brought me to a brand new welcome screen like the computer is being booted up for the 1st time.
Holding command r at boot time should get you to a screen that looks like this.
It's called RecoveryHD or if you saw a globe spinning it was Internet Recovery.
If you see something like a video and it's asking to set up the Mac like it was the first time out of the box, then that's Setup Assistant and that's a problem.
If you followed directions online to create a new Admin Account on the machine, then you entered commands into Terminal to delete a special file that keeps track if the machine was setup already, so it's showing you how to set it up again and will create a new Admin Account on the machine which of course then you can copy the files or possibly fix the other account.
If you are at the actual RecoveryHD as pictured above, then ignore that and look under the menu for Terminal and launch that.
and press enter, follow the promps on the account, you can just set a new password.
