Root Password Recovery


In Grub menu press e to edit the entry.
Use the arrow keys to go to the line that starts with linux and then press End to go to the end of this line. First add a space followed by init=/bin/bash rw


Press Ctrl-x to boot. The system will boot the kernel and run /bin/bash instead of its standard init. This will allow us gain root privileges without password.

At the prompt type passwd and enter your new root passwd ( twice ). After this type reboot and press Enter.

  1. In the screenie there is an underscore after init=/bin/bash rw_

    Which is correct? With or without?

  3. Isn't this rather serious for security? I mean root access by just changing the GRUB might make it easier for intruders.

    Yes, but you must have physical access to your computer.
