The Problem: so you’ve installed windows and all went well until you notice for some reason the 100MB system partition thats usually invisible in “my computer” is now visible and annoying you..
The Solution: in your start menu, right click on “computer”, in the submenu that appears click on “manage” the will open the “computer management” window. once there you’ll notice theres lots to look at.. but look to the left of the window and click on “disk management” this will list all the drives your computer has. a drive called “system reserved” should appear here. right click on it and click on “change drive letter and paths…” simply remove the drive letter using the window that opens.
