After my installation of Ubuntu 12.04, I removed the recovery console entries the from burg menu. I was messing around with user accounts and accidentally turned automatic login on. It, for whatever reason, did not keep the previously saved password and as a result will not allow sudo access. Every time I am prompted, my password is denied. I have tried leaving it blank and using the previous password with no avail. My computer is up to date and fully functional now (aside from sudo access which is essential for me), and I would like to keep it that way. So my question really is, what can I try to keep everything I've installed? Is there a command line hotkey for the burg menu that will allow me to boot from the recovery console despite being hidden and/or possibly removed?
