I wish it was free. It was free. But not any more. But this one is a gotta have. I have gotten myself out of some many jams I can't tell you. The grub repair is worth the money, works and it fast. Not terminal or scripts or anything like that. And it will allow you to grab stuff of a HD even if that HD will not boot.
You need this one in your tool bag. Pay Patrick the $$$ and get it.
