Sometimes fixing boot driver / registry / or HAL issues is plain more work than simply re-installing missing software & extracting personal data from a backup / image.
I'm not saying you have to as long as someone is willing to help you "fix" things to "clone, I'm just suggesting you may already have spent more effort on this than "Nuke & Pave" would have been, with potentially as much effort or more still to be expended.
Given a fresh install worked previously, it's worth consideration, unless you have totally unobtanium software installed that not even the Wayback Machine will yield installers for.
