Before you do anything else, back up *everything* before you even breathe on the system. You may think it's not going to reproduce agai= n, but if it does, you may end up losing more data. I tend to keep things very simple. Which is to say, I try not dual-boot Windows and Linux, and if I do, I use separate HDD's for the Windows and Li= nux systems. So if I were doing anything like this at all, I'd boot into a Li= nux system, and then copy everything from the Windows partition to the Linux partition in a single go, and then be done with it. The KISS (Keep things simple, stupid) principle is always a good way to follow especially with valuable data. And we're only talking about a 500GB HDD. Getting a second 500GB disk, or = for that matter, an external 1TB HDD or even SSD, is cheap, compared to the val= ue of your time. Backups. Backups. Backups. I've worked at MIT, and seen a graduate stu= dent lose ten years worth of their research data due to lack of backups. One c= ould perhaps claim that someone who was dumb enough not to make backups doesn't deserve to have a Ph.D., but regardless, it's still a tragedy; and totally avoidable. --=20 You may reply to this email to add a comment.
