If I try to clone my system disk with all my programs and operating system (Windows 7 Ultimate) on it, Acronis will not clone. I have tried through Windows and using the boot disk without success. I have disabled all USB disk readers and still no success. Acronis shuts down when I try to boot through Windows. I get a sign that it fails to clone if I use the boot disk and the computer shuts down. Are there any programs that interferes with Acronis? Any other suggestions? Originally when I purchased Acronis True Image 2012, it cloned my boot-programs hard drive well. Suddenly, for no reason that I can think of, it stopped. It will clone my data disk. I have upgraded it to the latest version and re-installed it with no success. I would appreciate your help.
