title: raspberry pi login fails
body: <p>I configured my RPi from a NOOBS SD from scratch - works fine - then I did a reboot and suddenly it asks for a login and nothing I try works.  I didn't change anything to make this happen.  Now nothing I enter will get me past this.</p>
  
  <p>This happened yesterday as well, so I reformatted the sd card - reloaded NOOBS - and started all over - you can imagine how long that takes - and now the same thing happens - what is causing this and what do I do now?</p>
  
  <p>Perplexed.  Need help badly.  Thanks.</p>
