To directly [1] use grub for dual-booting, it must be in the Master Boot
Record (MBR), since the BIOS gives control to the MBR when it is done.
This is, indeed, what should happen by default.

Maybe this is helpful for the OP:

[1] It is also possible to install grub to another disk and leave the
Windows boot manager in the MBR. Then one can use the Windows boot
manager to hand over control to grub. But this setup needs some manual
steps and I'd recommend it only if, for some reason, one does not want
to change the Windows partition at all, not even the MBR.
