You can boot it (using BOO, just like above) and it'll ask for the first and second devices as usual. But then once it's booted none of the tasks work - running INI, BAD, BRU all produce MCR errors (it says "MCR - error nn"; I forget the exact number, but I could boot it up again and see if you need to know). Those numbers would be helpful, but it sounds really weird that it would not work just fine... Give me the numbers, and maybe we can figure out what the errors are, and go from there. A full transcript would be even better. ;-) (Although I should probably also point out that you do not need to copy the file anywhere to use it. What it booted from is rather irrelevant. But then again, I could also be totally wrong...) Johnny
