Reinstall LINUX. I've had the same problem. I've tried everithing but it didn't work.
Reinstalling seems to be the only  available  solution, unless you have some info to backup. This is my opinion. Bye.

Did you recently add that user? Or did you install the shadow-suite? Have a look at /etc/shadow. If it exists and the new user isn't added, have a look at /etc/passwd. If the user's located there, run pwconv.

The filesystem must be mounted as read-only. Type mount to check that. I'm not sure if you can run pwconv in single-user mode, but normally you should be able to.

Did you check whether the user is added in /etc/shadow or /etc/passwd?

pwconv isn't available, but /etc/shadow is? Strange. The error message means nothing to me. What kernel do you run?

Check the amount of free memory on your HD. Can sou login as root in multi-user mode. Linux stops the login of nun superuser accounts if the amount of free memory on your HD gets low.
