Using Rufus (https://rufus.ie/en/) and a fast USB thumbdrive, such as Kingston DataTraveler Max - https://www.storagereview.com/review/kingston-datatraveler-max-review, you can make a "Windows To Go" installation.
Now you have a Windows install that you can boot directly from the thumbdrive when the need arise.
Perfect for booting up if your bios can't updated directly from the usb drive and forces you into Windows, or to run that one software you can't replace just yet and that refuses your attempts to run with wine.
Just make sure that it's an ssd usb thumbdrive or it's gonna be too slow to be any use.
