I have forgotten the administrative password on my laptop. I have tried booting into recovery mode as suggested but I don't get the menu where I can use the cursors to select recovery mode. All I get is a line of writing sayingS: 

gnu grub version 2.02 beta2-36ubuntu3.14

What am I doing wrong.

  • Have you forget your root user password or your not root admin user password?

  • GRUB is the bootloader, not a shell. It's where you select Recovery Console from early in the boot process. If your GRUB options are not loading, then your root password is irrelevant and this entire question is misleading - you have a GRUB problem, not a lost password problem. You may also have a separate lost password problem, but that does not matter until you fix or reinstall GRUB.

    Since you seem to be a rather new user, ADVICE: 1) Boot from a LiveUSB. 2) Backup your data. 3) Reinstall Ubuntu. Next time, don't enable root. Use Ubuntu the way it is intended to be used.

If you remember your admin user password You could login as a root user without knowing root user password using:

Open terminal and input the next:

  • sudo - su

or

  • sudo -i

When logged in as root with one of the above commands, you could change its password by command:

passwd

Admin user, but not root means that this user is a member of sudo group and could execute privileged commands using its own password, not root's.

  • Open terminal and enter one of those commands: sudo su for example. You will get root's terminal access. Being there you could change your root user's password by executing passwd command.

  • It's your usual user password you input when starting your system, except if you configured autologin. How do you login into your system?
