  Because I haven’t used my Ubuntu for a long time, I found that I forgot my password when I wanted to use it. After a long time, I finally got it right. Really…

  Record your new password here:Login password: 1234567; ROOT password: 1234567

  Following is the arrangement of online courses, pro-test can be used.

Step 1: ROOT must be retrieved before it can be done in the past.

1、Restart the computer by pressing the shift key until it enters the GRUB boot mode as shown below. Select the second line Ubuntu Advanced Options and select Direct Enter as shown below.

Step 2: Modify the login password

1.In VMware Workstatiom, click “Open this Virtual Machine”. Note that when you enter the system, you click the screen first. The purpose is to switch the mouse from VM to Ubuntu (otherwise, you may not enter the GNU GRUN interface if you press shift for a long time below).);

2.Click on the screen and press shift for a long time, and the system will enter the GUN GRUB interface (the operation of this interface can be seen below the description of the interface), as shown in Figure 1. If you enter the interface shown in Figure 2, the operation of this step will fail. Don’t rush to try again.

 3.In the GNU GRUB interface, select the Ubuntu advanced option and return to the interface shown in Figure 3. Select a system distribution number in parentheses that is recovery mode. I tried it. Both of them in Figure 3 can successfully modify their passwords.

4.Wait… You will see the interface shown in Figure 4. Select the root item and return.

6.Continue to enter exit and return to the interface in Figure 6. Select resume and return. At this time, a confirmation interface will jump out and then return. Then…. Quietly waiting for the login interface, haha, I wish you all success.
