New to Hackintosh, need some stuff cleared before I perform the installation and all.

I am currently using a fairly old MSI laptop with i7 7th gen, 1050ti and 24 gb RAM.

This is currently my main college laptop but I wish to use it for hackintosh once I upgrade, my main queries are mainly mainly regarding if I can run both Windows or Mac (either on same or separate SSD), or will the Hackintosh over write completely?, 2ndly it’s that can I get all the latest updates and all as from what I know, I can’t use Keynote and other Apple software on older OS.

Lastly this one is not important because I just want to know if the features like Universal Clipboard and the iPad (and iPhone) integration works as it would on a real mac or not.
