Normally this playing around is called “learning by doing”. This is no bad as long as you make your selves some notes so that you have them on hand when you do it again.
Here an other way how you can have windows and Linux side by side without messing around with your boot partition from the main computer.
This way you can use Fedora and Windows on the same time and when you really want to move permanently, you just remove windows an install you Linux as you learned in a virtual machine.
In first place we do help here to keep Fedora Linux running. There are users where like also to help with some window issues, but main focus is Linux!
