I recently got a pi and started making a webserver out of it. I quickly discovered that the directions I were following were broken. By that point, it was too late. Whenever I try to login as the user "pi", it will not accept any password. When I am in "root", and I try to create a new user it says that the user already exists. However, when I'm in raspi-config and I try to create a default bootup setting (ie. boot to GUI) it says that user "pi" does not exist. I've been struggling with this problem for days... Any ideas?
