recently I have encountered a problem with this, it is indeed not so straightforward to create a bootable windows 10 USB instillation media under linux.
The media created by fedora media writer is not bootable and the media created by ventoy lacks drivers. I was then able to create a media quite easily with the last windows machine in my household. I don’t know if it is a temporary bug or fundamental incompatibility.
So I would suggest you to keep a windows installation media at hand in case you need to switch back, or make sure at least one of your friend has a windows machine you can borrow.
