Lenovo p50 hackintosh

I have installed the Mac osx Sierra installer with clover bootloader to a USB. I was then able to boot into the setup and it asks where I want to install. If I format another USB drive, a 64 gb USB 3.1 drive and install it in there will anything on my actual pc be changed. I want to have it run 100% on the USB so as not to effect my computer at all. Is it possible? To clarify I don't want my computer's bootloader or anything to be changed. I want it to work only when I plug in the USB.
