Redhat 7 root password recovery

This is really a note for myself... since it is so terse with no pictures, but may be helpful to someone else. At the boot menu press "e" to edit the boot option find the vmlinuz line and after the root= entry find the ro entry and prior to this enter rw init=sysroot/bin/sh Press Control X and after it boots in single user mode... type chroot /sysroot passwd root passwd mount -o remount / touch /.autorelabel
