Ubuntu14.04 how to forget the root password

For windows operating systems, if you forget the administrator password, it would be a good solution.

One of the simplest ways is to use PE, a computer store, and old Mao Tao to solve this problem perfectly.

If it is a Linux operating system, it is actually very simple-single user login. The following uses Ubuntu14.04 to briefly demonstrate the specific operation procedure.

1. Start the instance, as shown in figure (no virtual machine is installed, and the pictures taken by the mobile phone can be used together ):

2. There will be an option: Advanced Options for Ubuntu, select and press enter directly, for example:

3. There are many options in it. select the option with recovery mode (do not press ENTER !), Press the letter e, for example:

4. The key time is up. The last and fourth lines will show a line of linux/boot/vm... ro recovery \ nomodeset,

Step 1: Delete recovery \ nomodeset

Step 2: Add quiet splash rw init =/bin/bash at the end of this line

5. Press F10 to start.

6. If there is no accident, you will enter the system, enter passwd, and the system will prompt you to enter a new password to end.
