My understanding is that the windows installer uses MBR if booted in BIOS
mode, and GPT if booted in EFI mode.  So make sure you boot it the way
you want it used.  Often the boot menu has two options for booting each
bootable device.  One legacy, one EFI.

And the boot loader had to be installed in the Master Boot Record (MBR) of the target hard drive.
