Copy Information To new SATA hard drive

I have recently purchased a new SATA hard drive. I have changed my motherboard for my Inspiron 9300 to have Sata Connections. Whats the best way to copy all my information from my old IDE hard drive to my new SATA hard drive?? Can i copy over the operating system also? Will it work straight away when i connect the new hard drive up to the new motherboard? Any help or advice would be grateful
