Patched OSInstall.mpkg and OSInstaller.framework to allow OS X 10.11 installation on MBR partition.
To use those patched files you must create an USB installer. You can't just run the app downloaded from Mac App Store.
After creating the installer, copy those files like that:
OSInstall.mpkg to /System/Installation/Packages
OSInstaller to /System/Library/PrivateFrameworks/OSInstaller.framework/Versions/A
