So I am looking to reformat my D:/drive (storage) as its just completely cluttered with crap. Anyways, I haven't done this type of stuff for a very long time. My SSD C:/drive contains my Windows OS. If I were to reformat my D drive would I have any problems booting up windows etc? I don't want to reformat my HDD (D drive) and then not be able to boot up the OS. I no longer have a disc of Windows to the best of my knowledge...
