This is so wrong. Windows has supported EFI since Vista.

Note : "stage 1" is a GRUB legacy thing. GRUB 2 calls it "boot image".

Moreover, GRUB BIOS cannot be installed without embedding (in a BIOS 
boot partition or any other suitable location) when the /boot filesystem 
is anywhere else than a plain partition (LVM, RAID, crypto...) or a 
filesystem type which may move block around such as btrfs, defeating the 
hardcoded blocklists.
