Well, I feel a whole lot better now (emotionally) after that pleasant but challenging exchange, however some of my initial basic questions about mbr.exe remain unanswered…

When I ran mbr.exe it gave me an immediate black screen then my computer auto-rebooted. Is that normal? What exactly did it do to my computer, if anything?

Should I have run it in the avast sandbox, as I was advised to do by avast, or outside of the sandbox? Is that what caused the black screen and autoreboot?

Maybe I shouldn’t be running it at all, and I don’t plan to run it again, but I’d like to know what happened, and why. Apparently a lot of folks are running it these days without knowing the consequences. Give a monkey a banana and he’ll eat it. :slight_smile:
