Where I work, I need to donate a computer that I have in order to have a computer that works better than what I have available. In doing so, they must clean the HD and install their OS and Software for which they have licenses for. What I would like to do is install a second HD that I will be able to use the computer with the OS and Software that I have purchased. Is it possible to run one OS and programs from one HD and then have the option to reboot to another OS and software. Is that possible?
