Those instructions are not up-to-date....

On this page, just check the "Configure advanced boot loader options" box and press "Next" to continue. If you have entries other than "Fedora" in that list, you may want to remove them for a smoother dual-boot procedure later on.
The "Configure advanced boot loader options" box went away many Fedora versions ago. It was replace by the "Change device" button. After clicking that button, a pop-up appears with an obvious choice for installing GRUB in the first sector of the boot partition. So, did you recognize that and do it that way? Otherwise, you may not have GRUB installed in the first sector of the Fedora boot partition. It's required for EasyBCD to work if you do that step in the "Linux" tab of "Add/Remove Entries" in EasyBCD.
If you did notice the change to the Anaconda layout and properly installed GRUB in the first sector of the Fedora boot partition, then maybe you are choosing the wrong partition in the "Linux" tab of "Add/Remove Entries" in EasyBCD. It's not that difficult for anybody to get partitions wrong.
