I've not returned here due to a major disaster, with much data lost, much time lost, or more succinctly, too much.
I was getting ready to try one last ISO attempt, this time in Clean Boot. As you cannot actually turn Comodo Firewall off, and as there is a plethora of advice about this, I was in the process of uninstalling it. The last step is to restart, which I did; to my complete dismay, Windows had absolutely no WifFi; the only way to fix that was to boot the ISO and replace Windows.Before I did that, I did some research, and bought EaseUS PCTrans, hoping that it would recover at least a good part of my now-ruined Windows, and then I expected to use my Macrium Reflect backups. Given the strange difficulties I had been encountering, such as not being able to install an ISO, I suspect that my copy of Windows had been in a slow process of becoming corrupt before the WiFi catastrophe.
Ran PCTrans, then replaced Windows,and ran the the program restore function of PCTrans, which did restore many of my programs. It has a separate module for restoring files, but only did so for two, which happened to be among the most important to me. I corresponded for while with EaseUS technical support, which seems to have given up, and to not even told me why. I discovered that I could simply copy and paste anything in the file module that I wanted, so I've not bothered to contact them again. I also intend to use the program's set-up a new computer module, as I am about to purchase a new one; my wife shall inherit mine, and hers (which was mine) is nearly six years old shall be donated.
Having done that, I opened Macrium Reflect to do further restoring, only to find that my backup files were corrupt! I've been slowly doing what I can to remember some of the missing programs; in fact, today, I figured out what to search for and found and restored one missing program. Some of my material is in Dropbox, but given the slowness of my DSL, not as much as should be there. Last Monday's full Reflect backup is 53,704,291, and, yes, I have checked and it is accessible, not corrupted.
There are many things that are gone. sic transit gloria mund
