Both the options give me same result-:
root@place:~#

But the problem persists id I try to be root by being any other user with the options you mentioned it again says
NO Shell.

hello,
Is there is anyone who can guide me further.

suggest that you're logged in as root.

This means that part 1 of the solution, namely to give you a shell with root access, has worked. The next step is to actually fix root's login shell settings in the /etc/passwd file, that are causing the error.

So, at the above prompt, open /etc/passwd file in your favorite text editor, go to the line that contains the entry for "root" user and modify its last field (changing "bash" into "/bin/bash"). Then save the file & exit the editor.

Alternatively, just type in "chsh" at this prompt. If it can't find the "chsh" command, don't worry, and revert back to editing /etc/passwd as I mentioned above.
