Factory Image Recovery problem.

Hi. So i was having some problems with a used Dell Inspiron R15 5520 Win 7 laptop. I did a Factory Image Recovery by going to the boot menu (f8 on boot up) and went to repair computer, went through the process as directed and had a successful recovery. When i restarted the computer it went through all the loading screens it was supposed to and gets to where it says "Setup is preparing computer for first time use.....Setup is checking video performance" then it goes to the user log in screen with a blank profile picture and ask for a username and password. I put in Administrator assuming its the same process as the repair computer paradigm and then it says "Your account has been disabled. Please see your system administrator.". Anything else i try it just says "The user name or password is incorrect". I've tried doing another Factory restore and same results every time. What do i do?!? Any help on the matter would be much appreciated. Thanks in advance!!
