How to remove dual boot bootloader

So I want to install hackintosh on my pc in the same drive as I will be waiting 1 month for my second ssd to come. So I want to try macOS and install it on the same drive as windows. What if I follow this guide ? When I am going to install macOS on the other hard drive how I am going to remove the bootloader of this ? Am I going to install windows again or I can do all a the steps I done in reverse ? Also is this guide working ?
