I am currently running windows 7 64bit.  I was having issues with my BD 2015 interface so it was recommended that I run a repair.  I did this and then it said to restart to finish.  I restarted and low and behold no windows.  It will only start the start-up repair function and it does nothing else.  I have ran the repair multiple times and it wont fix it.  I can access the command prompt but have no idea what I can do with that.  I am completely lost as to what to do and chat here at BD says they need to escalate the issue and it can take a couple of days.  I really hope someone here can help me.  I paid for this ###### program and I don't want to have to format and lose a lot of important things because of their repair not working.  Maybe there is someway I can bypass it booting any bit defender files?? Please help me!!!!
