Problems When You Try to Log In If you did not create a user account in the firstboot screens, switch to a console by pressing Ctrl + Alt + F2 , log in as root and use the password you assigned to root. If you cannot remember your root password, boot your system as linux single . If you are using an x86-based system and GRUB is your installed boot loader, type e for edit when the GRUB boot screen has loaded. You are presented with a list of items in the configuration file for the boot label you have selected. Choose the line that starts with kernel and type e to edit this boot entry. At the end of the kernel line, add: Press Enter to exit edit mode. Once the boot loader screen has returned, type b to boot the system. Once you have booted into single user mode and have access to the # prompt, you must type passwd root , which allows you to enter a new password for root. At this point you can type shutdown -r now to reboot the system with the new root password. If you cannot remember your user account password, you must become root. To become root, type su - and enter your root password when prompted. Then, type passwd <username> . This allows you to enter a new password for the specified user account.
