Thanks again Jim,
I have repartitioned drives to use puppy linux on a windows machine, so I know it can be done, but I think it’ll erase my current OS drives when I restructure the internal HDD. I’m not sure that I’ll be able to solve that as the software comes from an educational “lease”. If I need Lion re-installed on here, I’d just be sending it back to them to re-do it. That would hit a brick wall. If I just go back to snow leopard, I’m worried I’ll lose some of the drivers. (?).
I’m not to sure about installing it from an external drive… That may be the way to go… I’ll keep digging in the meantime. Cheers for that!
