The last command you typed was "passwd root" and the normal response you should have given it was the new password for root, followed by return key and then it will prompt you to type the same thing again (so that there were no undetected mistakes). Then it will confirm that it has changed the password.
Note that when you use the "passwd xxxx" (for any other non-root password) it prompts you for the current password. See the man page for "passwd" command to get the details.
Bottom line, is that it will sit there forever waiting for you to enter something. So give it something to continue the process of changing the password.
Good luck…
Ahh, i thought you typed passwd root <return> and then it would prompt for new password. Either way I backed up, formatted and reinstalled. Thanks for the help though.
