So I'm on the verge of installing Windows 8.1. In the event of a fuck-up, I'd like to be able to restore the contents of my C: drive to EXACTLY the way it was before installation. Most cloning software should allow me to do this, correct? Ideally, I'd like to be able to create a copy of C: on another internal drive and restore from that if 8.1 boots up and there's something severely broken. My concern is that the restored version won't be a 1:1 copy or problematic in some way based on the sensitive nature of boot files.
