To install Windows2000 Professional

I want to install only Windows2000 Professional as a Operating System in my PC. So, my question is can I install Windows2000 Professional without installing any previous version of Windows Operating System? Please also tell me where I would find the option to make a start up disk in Windows2000 Professional ? Can you provide me a information that where I would get a freely available burning software by which I can make a CD bootable Windows2000 Professional CD.
