Neither one will reboot from the other and you will end up with the вЂњNo bootable deviceвЂќ error.No one has solved this yet and I cant believe after all these years Apple still hasnвЂ™t addressed the problem with a simple fix. Either way, youвЂ™re still left with a Bootcamp partition thats seen in the Startup Disk control panel as Bootcamp that the Mac WILL NOT reboot into unless you are holding the option key at startup, and vice versa when youвЂ™re in Windows and want to use the BC Control Panel to reboot into MacOS. Insert Windows USB installer, reboot and hold option, select the EFI Boot, reformat your partition, install Windows.Saves people the step of possibly screwing something up big time with gdisk and you end up with the same result.
