Long story short:
On this server I had lost the password to the server root account, as well as a secondary non-root account. Thus, leaving me powerless to change the non-root password (or to do anything for that matter).
I've finally been able to login as root by changing the Ubuntu 14.04 boot to have
rw init=/bin/bash instead of
quiet ro splash.
Unfortunately, anything I do as this root is completely virtual in a sense. Any files I create as root disappear the next login. Not to mention whilst logged in as root, all other accounts on the server apparently don't exist.
How can I recover (proper) server root access that will allow me to alter files/change passwords?
Other things to note:
- The bios and grub menu are password locked as well.
