If I create a proper LiveCD and run the OS from the disc does it save any information on a hard-drive or is it ALL saved to the PC's memory? I've looked around for a clear, direct "yes/no" answer to this question but I can't seem find it anywhere. Common sense would say yes but you never know and what I need to do requires an OS that does not use Flash(usb) or Magnetic(hd) storage of any kind while in operation. Thanks!
