If you went in via a Live CD, and mounted the Debian root partition,
the next step is to chroot into the Debian root partition. Then you
can run "passwd root" in the chroot shell. Then exit from the shell,
and unmount the Debian partition.
Of course, your way (which I'm assuming is "mount the Debian root
partition, edit the /debian/etc/shadow file to clear the hash, unmount
it, reboot into Debian, login as root with no password, and run "passwd")
also works, but it's a bit more effort.
