To start, I'd read this, then come back if you still have questions 
about logging in.

https://help.ubuntu.com/community/RootSudo

Further, please explain what you mean that you can't log in but you can 
use 'bash'.  I doubt you'll have any shell, bash or otherwise, without 
first logging in.

If you're talking about logging in as 'root', that's not available 
without specifically enabling it (in Debian and derivatives, such as 
Ubuntu).  The security model in Debian flavors of GNU/Linux call for the 
use of /sudo/ when root privileges are needed.

Of course, I may have wholly misunderstood the question(s) - if that's 
the case, sorry for the noise.
