The System Image Recovery
I am using another way to recover my Windows 7 Ultimate instead of using System Image Recovery method. I use Macrium Reflect backup and restore with a USB hard drive which I had partitioned before using it. I had back up 'C' and 'D' drive separately everytime once I'd install a new program and ran it for a week to make sure there's no problem or issues. Of course, I also use the Windows Restore Point before install any new software.
Anyways, I found this maybe the best for me because it does not take too much time to use Macrium Reflect to back up and it is better then the others that I had use before; like 'Ghost'.
Oh, best of all, Macrium Reflect is FREE.
