So I decided to make the huge leap and actually (finally) got a macbook pro, which I love already. I would like to take my old XP OS and install it on the new mac using bootcamp, so that I can run Solidworks and Labview. I know that I can only use the operating system on one computer, so I will no longer be using the old one. My question is, if I still have the key, but not the discs, can I still install the OS and bootcamp or do I need to buy a new one? Also, I don't have my Microsoft Office 2003 key or cd's anymore, but I would like to switch that over as well. Will I need to buy it again, or is there some way to get that off of the computer? Thanks a lot.
