Planning to make my laptop(HP-AU006TX) a hackintosh.

I have an HP Pavilion laptop, with a single 2.5 inch HDD. I want to add macOS. I plan to put the HDD in the optical drive bay with a caddy(SATA 2 connector) and an SSD(with macOS) in the main slot(SATA 3). I have read somewhere that it might not be possible to boot Windows 10 from the HDD in the caddy. Please tell if the idea is possible and if it's a good idea.
