Browsers are only a means to go online. Chrome, on install, should ask if you want to import favourites from IE, so select yes. You can have IE open and Chrome open at the same time. If you want your home page the same in Chrome then copy your home page address in IE then paste in the address bar in Chrome. Go to the 'tools' section in Chrome (an icon like a blurry letter I believe) on top right then find out where it is to set the home page and insert the address.
