Why don't you have the root password? Is this not your system, but just
one you've been given for ordinary use?

When booted from a LiveCD or with a different init, check to see what
information may have made it into logs from the previous failed boot
attempts.
If nothing has, you might see if you can get any information out at the
time of the boot failure, over a serial console or netconsole. (Good
luck with that; I've never set one up myself, although I know the kernel
developers use them routinely.)
Make sure you have a valid init installed and configured, by
reinstalling the appropriate packages ('apt-get install --reinstall
packagename') if necessary.
There's not really anything I can say to suggest the possible actual
problem without knowing what the messages around the "hang" and/or the
"drop into emergency mode" failures are.
