How do I restore my fusion drive back to its original state?

Long story short, I installed Windows 8.1 and things worked perfectly. I upgraded to windows 10 then my mouse and keyboard features stopped working. Tried to get Bootcamp windows assistant software for the drivers but accidentally saved it to my Bootcamp drive. Got an error and now windows is gone. I tried to reinstall windows 8.1 but I received an error that the volume is't accessible or it doesn't exist. (Boot camp worked perfectly the first time around! 😟

Now...I tried to manually make a partition via Disk Utility and it never completed so I forced quit...Now there is a virtual drive (wasn't there before). Not sure what is going on. Can I restore my drive to its original state? I've already backed up files to a drive so I am ready to do whatever is needed.

Are all of these partitions normal? I'm new to mac

I have late 2015 5k retina i5 Mac.

You still have a Fusion Drive configured, so all you should have to do is restore the data from your backup.

Are you referring to time machine? I never used it. This computer is new and I only started looking into using its features =\

You wrote that you had backed up. How did you do that? What is the state of the startup volume now?

Sorry what I mean by backed up was I moved all my pictures to my external drive. It's all that I had on the computer. Its fairly new. Everything boots up fine but now I can't install windows. When I force quite the disk utility as it was shrinking the volume and this virtual drive showed up all of a sudden.

The virtual drive is the Fusion Drive logical volume. That's normal. If you're having problems with Boot Camp Assistant, I suggest you post a question in the Boot Camp forum.

Enter "man diskutil" in the Terminal window.
