Well I agree with what over user has sad here view entire the over distros that are observed over will dual boot with Windows 7 and let me tell you that they are all simple to set up and utilize. If you have plenty bandwidth and better net connection then try downloading few live CDs such as of Fedora, Mandriva, SuSE, and Ubuntu and try utilizing then in your system. If you just require a better suggestion from my side, then my vote goes for the Ubuntu. It will do all you require it to. So hope you have got the require recommendation that you were appearing for.
