I found a reference to this problem here:
http://www.linuxquestions.org/questions/fedora-35/fc2%3B-vfs-cannot-open-root-device-label%3D-or-unknown-block-0-0-a-269230/
that described how they had solved the problem, and said they found the
solution here:
https://bugzilla.redhat.com/show_bug.cgi?id=126953
Maybe it will point you in the right direction.  From their description
it sound like you have to run mkinitrd (on F12 that will work, it seems
to be gone from F14 so you probably have to run dracut somehow on F14).
