Please help! I need this fixed ASAP!

Hi, I used your steps to reset my laptop. It was all working fine and it did reset the laptop but once it had restarted and went to the login page and I typed in my password it loaded up to a page saying:- preparing your system
This might take a few minutes
The system will restart automatically
Please wait....
The laptop then restarted and went back to the login page, I typed in my password and the same page came up saying preparing the system???

Why is it doing this and how can I get it to stop and just load up the laptop properly???

Please help me
