This is the GRUB menu.  You can choose which entry to boot, and also
edit the boot command lines before you select one.  So, if you need to
add or remove kernel options, select the line with your cursor, and hit
the "e" key....  If you read the screens, they should be mostly self
explanatory.

One of the things to remove would be the "rhgb" options, and possibly
the "quiet" option as well (is that two options?)  Then you can see what
the startup is doing and you can then report back the last few messages
on the console or some errors that happen during the boot up

Another thing to try is to boot each Fedora Live image between FC20 and
FC23 to try and see where the failure starts.  Especially, if FC23
doesn't work, does FC22?
