You could run it on any other computer without affecting it by using "virtual machine" software . It runs the operating system inside of your own operating system but they don't affect each other . It's an emulator in other words , if you are familiar with that concept .

Probably not what you want though , partitioning your harddrive and doing dual boot will be way better , just make sure to give it enough memory for what you want to do , most people split the SSD / HDD in half .
