win8
is secureboot enabled ?
secureboot is a veiled attempt to kill off installing any other OS besides win8
do a search on the FedoraForum for " win8 " and " secureboot "
http://www.forums.fedoraforum.org
and if this is an ARM laptop
forget about dual booting
you use win8
or flash everything ( to remove the secureboot firmware) and install linux
