Oh no! I can't log in!

I recently got Ubuntu 12.10 installed on my computer which currently has no other OS. Unfortunately after the installation it asks me to log on, when I enter the correct username and password, it says it is invalid everytime. I have tried uninstalling and reinstalling multiple times and I'm still getting the same result. Anyone know a solution to this problem?

Well, you are typing it wrong. If you are using locale keyboard, make sure the correct one is selected because the letters you are typing might be different otherwise.

For resetting your password using recovery mode:

Please also be aware that passwords in ..x are case-sensitive, so check whether you have pressed caps lock. If it's a laptop you might also want to check whether Num Lock is activated, as this can interfere with the keys on some laptops.
