The selected disk is not of the GPT partition style”Īpparently, BootCamp formats the disk to FAT but the partition scheme stays GPT. Windows cannot be installed to this disk. However, when I run Bootcamp Assistant and I go through all the stuff, when the Mac reboots into Windows installer I get the following message: However, doing it this way has been causing some weird issues so I am trying to get it done via the appropriate Apple supported way. So I have been struggling for several weeks now with BootCamp.įirst of all let me say I have successfully installed windows 7 & 10 via the non-official way by formatting a partition to FAT + MBR Boot Scheme. System: 2009 Mac Pro, upgraded to 5'1 firmware.
