Besides, in dual-boot with Win8 starts anyway and always Win8 or only Linux.
That less to do with mentioned (unetbootin) package but more with Grub/OS-prober not let start Win8 anymore.
The past solution with Easy-BCD don't work anymore besides if Win8 cannot start the user has no more possibility to run easy-bcd.
Maybe that's the occasion to think about a bootloader (e.g. rEFInd) capable to boot Linux, Win8 & Mac with appealing look.
The actual solution with deactivating 30_OS-prober, read ESP/EFI-partition-UUID and set manually a chainload in 40_custom is a roundabout way or not user/newbie friendly
