Good god man!, Just use Google to search for info on different distributions of Linux, it will be much faster and you will learn more than sitting around waiting for someone to respond to every question you have. Or better yet, go to the websites for different distros or if you want a list of distros go to http://www.linux.org
If you dont know anything about creating multiple partitions I would hesitate unless you dont mind losing all info on your computer if something goes wrong. Just a word of advice
