There’s no such thing? You’ll have to install windows just like you installed Linux. I’m confused how you got Linux on your machine yet you’re asking this question-did someone else install it for you? If so, best to not mess around with repartitioning your drive. High likelihood of you screwing up your boot partition. Best to jam in another hard drive, unplug your Linux drive and go to town. Or heck, do what you want and learn :) breaking things is the best way to learn…
Just please back up all your files before you go crazy. You can’t permanently damage or break anything on your computer, but you CAN permanently delete files you cared about :)
