I was changed the /etc/fstab file to permanently mount a USB drive, but when I rebooted, I was welcomed with an emergency mode message. However, below the message it says my root account is locked and so I cannot use any commands to fix this issue. Is there a way I can still regain control of my computer? Will recovery mode help me solve this issue?

Here is the message it is displaying:

You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or “exit” to boot into default mode.

Cannot open access to console, the root account is locked. See sulogin(8) to continue.

Press Enter to continue.
