    I would install a fresh copy of ubuntu 14lts. You coudld aslo look up the root user name then change the root password and add user but this task is daunting.

  • You people seriously downvote a newcomer to the fun land of Ubuntu, unable to login? :) Shame!

  • I don't understand why Dell pre-installs a guest-only Ubuntu in their notebooks.

You can user recovery password procedure to gain admin 1. Use this link to gain access to shell 2. Get list of existing users and find the admin username (and change his password using the above) or add new admin user. You can find details in this link on how to get list of users and adding a new username.

Best way to do is add username in /etc/sudoers file with full permissions and then use "sudo passwd root" to set new password

    /etc/sudoers is owned by root, how will he edit it with his guest account? Please describe how to achieve this or link to another answer. If you intend to link to external sources, please copy the relevant parts here, to make sure the information is always available.
