Go to the line which the word kenel at the start. You press e again to edit it and append an S to the end of the line. Now you press <enter> to accept the changes followed by b to boot the kernel with the modified command line.
You will now be presented a single user mode bash shell to repair your system. It seems complicated but it is easies as you think.
