The below program is not free but believe me it is well worth the £25. It has helped me out many times to get my computer up and running again in less than an hour. Believe me it is £25 well spent. A bit of advice if you do buy it, you can save yourself £15 by purchasing from Amazon.
Acronis also has an excellent forum as well, I have always found them very knowledgeable when I have needed help.
