I am shortly going to be downloading the trial version of Acronis True Image 10 on a view to purchasing if I like it and can work the program. But I have a few questions first that I would like answered please, I have a Western Digital My Book Firewire external hard drive, which I am wanting to use primalary for backing up my PC's C drive. I was wondering what procedure would I have to do from start to finish to be able to restore my PC in the event of either a operating system failure or a partly corrupted operating system. If I had an operating system failure and my PC would not boot, how and what would I need to do prior to this happening to be able to restore it, and what is the procedure that is required to restore my pc to a state when everything worked fine. Also what are the best methods to use In Acronis true image 10 for backing up to my external hard drive. My worse case scenario would be these, If I had a problem with my pc, and when I switched my pc on it got to a point just prior to it starting to try and attempt to load up Windows and then failed to load, how would I be able to restore my PC to a working condition off of the external hard drive, i.e everything working fine, all my programs and everything else would be working fine. If I installed some new software/hardware, and I then found out that I was having problems and I wanted to restore my PC to a time when everything worked fine how would I do this, I understand that I would be able to use system Restore but if this would not work how would I then do this. If anyone can answer all my questions I would be very very grateful.
