How do I create an image file of my hard drive

I have used Ghost for years at work to create images of the hard drives for specific model computers. I purchased Ghost 14 because I am running Vista Home Premium and wanted to create images of my c drive. I can not for the life of me find out how to do this :smileysad:.  I wanted this so if the machine crashes I can just restore the hard drive and be up and going again. Please help.

 

Thanks in advance
