That's true Patio. However I prefer Norton Ghost, so that was my recommendation.
chiragsk,
Your best bet is to use Google to search for the product you want to use and then read the documentation on it. Most products will have a step by step guide.
Here's a link to
Acronis's website. It's a cost effective product and looks like it will do the job more than well enough.
And a link to
Norton Ghost as well. If you need any further help just let us know. But before you rush into this, take some time and read first.
