I'm working on my first build, and I got ahead of the instructions and installed Windows before making any partitions (following Newegg video). It's up and running but I haven't installed any drivers yet, because when I went back to the video I realized I hadn't created partitions first. Is this a necessary step? I've done some searching and there's a ton of posts about partitions, but I'm not getting any answers on why we install them and if it's always a necessary step.
 
Solution
A partition is generally a good idea because if for some reason you have to do a clean install you don't lose all data on the drive.

Just to follow up on this, it looks like my computer automatically created a partition for me when I installed Windows, so that's great in case I ever need to do a clean install. Thanks for your help!
