I am new to software development. As Linux is open source project & open source code can be modified by anyone, I need to know where to find the Linux source code on my machine & how to modify it?

I want to try a Linux based OS on my machine as dual boot system w/ Windows Vista. Found lots of info in net, tried Ubuntu Live CD (without install), however cannot decide which OS will be the best for me. I’m not experienced w/ Linux and just want to try open source soft. I researched all of these distributions http://www.linux.com/distributions/ Is out there something else I don’t know about? Also the question is which distribution will work the best on my machine which is HP Pavillion dv9420us, see http://www.shopping.hp.com/webapp/shopping/product_detail.do?storeName=computer_store&landing=computers&category=notebooks/dv9000z_series&subcat1=rts&catLevel=3&product_code=GA354UA%23ABA&tab=detailed_specs#defaultAnchor Thanks!
Can I try other OS without installing them (like Ubuntu)?
