Is this possible to turn into a Dual Boot hackintosh?

I have a PC - which I’ve already checked and it is compatible for making it a Hackintosh. I’ve recently added a GTX 750 to make the graphics compatible (High Sierra)

I currently have Windows 10 installed with all my data - Legacy BIOS. Is there a way to partition the existing Windows 10 drive and install MacOS on it even though it is a Legacy BIOS?

Any guides linked would be appreciated - If the hackintosh is stable enough I might remove Windows 10.
