Over time I have accumulated several genuine Windows Versions (XP, Vista, Win7) on separate HDD drives running on the same machine. Now I'd like to combine all three OS onto one SSD with a multiboot option to boot one of the three OS.
A fresh install of various Windows versions onto one drive in different partitions is very well possible. In fact Windows simply creates one Startup option for each OS installed. However in this case, I do NOT want to make new windows installations, I want to clone (or merge) each of the three OS on a single-drives onto one SSD. How can this be achieved, so that each OS residing in its own partition can be booted from?
I have taken a thorough look at various options discussed on this exchange "What utility can move my Windows boot partition over to another hard drive?" and also How to clone a Win7 boot partition onto the SAME hard drive? Unfortunately I did not succeed.
Some use AOMEI or MiniTool, one person using easeUS gave a nice and detailed description but also mentions that the proposed procedure isn't tested.
What I am hoping for is to receive advice for a working solution from someone who actually did it and has verified their suggestion.
I have the option to use gParted running on a Raspberry Pi 4. Therefore a solution that involves Raspbian is also very helpful.
