I'm about to upgrade my computer but might keep some parts. Just wandering what I would have to keep to prevent me having to reinstall my OSs, at the moment I have a dual boot setup with ubuntu and windows 7. I'm pretty sure you can't just take your hard drive with the OS on it and put it into a different box and keep going (can you?) but I know you can change the graphics cards, secondary hard drives and ram with out a problem. So what is it that you can't change? The CPU? Motherboard? Thanks for any replies
