ThinkPad T480 Hackintosh

I successfully hackintoshed my t480 to macOS Ventura, but I want to dualboot windows and macos, I want to try mountefi but there is a risk of corrupting the windows boot loader, yes o have read the guide but I don’t understand it, as far I understand I will have to mount my MacOS partition and mount my usb, now the part I don’t understand I will copy the efi and oc folders to the macOS patition?? Or the ssd where is also my windows?? I actually don’t know, after that I will just change the boot option in bios, but from what I read from YouTube comments some people ended up corrupting the windows boot loader, so I actually don’t know what to do, please help, and if you’re gonna just paste the guide, then don’t do that just completely ignore it, thanks in advice!
