ok this is what i am trying to do. Get a Wii emulator on my PC without it really being on my PC. i have a ssd and a hhd winch i keep clean and i intend to keep it that way. but i have a spar old hhd laying around ( its 80g and 5400rpm and running window [idk the version}) so here is the question can i boot my pc from that old hhd and get what ever i want on there and not have it touch and if possible not see my other drives?? thanks
