Thanks for the reply; however this procedure from the link provided, doesn't work. Here are the steps I that failed for me:
#5. Use the Arrow keys to highlight the line that begins with kernel and press the e key. 
- There was no line starting with the word "kernel".
#6. Go to the very end of the line and add rw init=/bin/bash
- I added "rw init=/bin/bash" to the last line (without quotes) but the next screen after the boot process echoed "error: unknown command rw".  It then went to the regular login screen.
What am I missing?
