This is because the root Super User is disabled by default in fedora linux.

Make the following changes.

Enter repair mode, and enter the following command to modify:
Enter the command: vi/etc/pam. d/TPD &
Comment out "auth required pam_succeed_if.so user! = Root quiet "(add" # "before this line to change it to # auth required pam_succeed_if.so user! = Root quiet)
