Locked myself out of my computer?

I swear I'm such a dumbass I was being all cocky b/c my sister figured out my password so I changed it and made the password hint "hey you get off my computer" but I can't remember what it is. I have a Lenovo with windows 8 and I have one of those photo passwords set up, but I got it wrong too many times because the lines I was drawing weren't exact (I do know my photo password, if that helps) so basically then it auto sent me over to my typed password and I ant remember that one. It is not my Microsoft password. If I click the reset password button it says I have to enter a password reset drive. Do I need to take this to the store, if so which store? Or is there another way around this?

You will probably need professional help, and you might lose all your personal files that you had on the computer, so I hope you were sensible and kept regular backups.

Reboot, F2, security, change password
