I have an 2011 macbook which has been updated to EFI 1.7.
Bootcamp sets up a hybrid MBR to support Windows 7.
I need to install Windows 10 on this hybrid MBR setup instead of an EFI/GPT setup because the Cirrus audio chip doesn't register itself on an EFI/GPT setup for whatever reason.
The problem is that Windows 10 prefers (U)EFI GPT hard disks and refuses to install on a hybrid MBR citing that it can't install on an MBR partition in an EFI system.
How can I force Windows 10 to install on a hybrid MBR setup and bypass the EFI/MBR error it gives upon install?

Enable Legacy mode and boot to the installation media. Windows on a hybrid MBR/GPT. The answers to those questions still apply to Windows 10, nothing, has change since those answers were submitted.

You can do the hybrid-to-protective conversion by re-writing the protective MBR area. Some tools, like libparted in Linux, do this automatically whenever you make any trivial change. My own GPT fdisk (
