Does anyone have any knowledge or suggestions about how to clone a dual boot computer system? What kinds of methods might be used to achieve this goal? Do I need an external hard drive disk to save the data onto? I heard that a bit-by-bit copying process could do the trick. I want to clone my whole computer into another machine, or the same one to revert it to an earlier stable state.

I would like to make a copy/backup in such a way that I would be able to take this backed-up data, and use it to overwrite my computer to that backed-up state if anything goes wrong, or overwrite a different computer to give it the contents of the backup. I have a really customized dual boot computer system, and a lot of installed software. I would like to make a complete copy of both operating systems, the relevant files and programs, my personal data, in short - a complete copy of the whole computer.
