The Boot Camp forum is probably the best fit, here at Apple. And it appears Windows isn’t happy to find a GPT device.īut again, High Sierra is not the best spot on the Internet to ask Windows legacy bootstrap questions. It also seems that Windows must be installed on the main boot device. Or follow the other link and use ESXi or equivalent, as that and similar packages can present different boot-time environments to the guest operating systems. You know this, of course.įollow the link in my previous post for one possible way to enable the MBR legacy boot path that you want to try to use with Windows. Recent Windows and macOS and most other systems use GPT, as does Boot Camp. GPT (with a protective MBR), MBR, and the older Apple Partition scheme. The only MBR that’s present in the usual Mac configuration is the so-called protective MBR that’s intended to prevent the GPT from getting clobbered by the older MBR-only tools.īoot Camp adds a layer atop that to allow Windows to recognize and boot on an Intel Mac.įolks most knowledgeable in Boot Camp and its operations tend to be over in the Boot Camp forum, too.ĭisk Utility allows three sorts of partitioning on macOS. Loner_T was referring to Boot Camp and how Boot Camp presents the Mac hardware to Windows with that quoted image.
