I have three internal hard drives. One runs on Windows '98, one on Windows 7, and one on Windows 8. I also have an external 500GB SSD. In the end, I want to get each hard drive to be a partition on my SSD, so that I could boot any of the three partitions from my SSD on my laptop. There's no real reason to do this, I just thought that it would be fun and nostalgic to see my old, crappy computers run on high-end hardware. I know that just copy and pasting my files into my SSD isn't enough. I forgot the technical details of how to do what I want to do. Can anyone remind me of the details of how to do this?
