If you have the port and money for it, I’d recommend a separate drive for the second OS. Windows is kinda notorious for stomping over GRUB if you rely on partitions for your dual boot.
If you’re worried about installing to the wrong drive on accident, you can always physically disconnect the existing drive until install is complete, then plug it back in and set the boot order in the mobo config.
