and welcome to linux.org
I think if you type into our search facility top-right
dual boot windows
you'll find 191 references to get you started on how we help people to run Windows alongside Linux.
Search is restricted - "run alongside Windows", "keep my Windows" &c are all permutations that would reveal thousands more examples here.
If someone says they wish to keep their Windows ... we help them.
If someone says they want to replace their Windows with Linux, we help them check they have personal data safeguarded, and that they can continue to get the functionality of Windows apps in a Linux environment. We recommend alternativeto.com to that effect.
For FOSS apps that are cross-platform, such as Libre Office, Open Office, GIMP, Firefox, Thunderbird, and hundreds of others, users can try them in Windows first.
