problem description
how to partition a removable hard disk under windows so that one partition retains the original file, one partition is written to the linux installation image, and one partition installs the linux system using the image in the previous partition? (I just want to have a plug-and-use linux system installed on a mobile hard drive.) in addition, suppose you want to safely delete the linux system after installation, what are the things you should pay attention to? What software is better to do these things on windows? (preferably advertising-free, reliable, open source software)
the platform version of the problem and what methods you have tried
windows platform. At present, I have not tried because of the limitation of knowledge. (the boss who wants to answer can remind you what knowledge you need, such as file system, boot)
