Raspberry Pi If your Rasberry Pi (RPI) won’t boot and is showing “Cannot open access to console, the root account is locked.” on the boot screen. Don’t sweat. It can be fixed with a little work. You were probably editing /etc/fstab and have put in an unsupported entry. What’s happened is now on next boot it’s tried to load this entry, which doesn’t work, and it’s locked the Pi from starting up. ..
