Bootcamp Help Please!

Hey everyone, new to the Mac Forums so I apologize if this is a duplicate post. Just haven't been able to find a solution.

Here's the problem:

I have a late 2013 Macbook Pro Retina running OS Sierra. It has 128gb of storage and 104gb is free. I am trying to run Bootcamp to install Windows 10 (I bought a Windows 10 installation usb from Best Buy) but when I run Bootcamp I get this message:

"The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."

If anyone could help that would be really appreciated. Especially if the solution is laid out easy and straight forward.

Thanks!

See minimium requirement below and it MUST be in a single partition when starting. There is no getting around this by hook, by crook or any other way.

My Macbook meets all the requirements but my problem is that I don't know what to do now when I get that error message. Can someone help with that?

If you open Disk Utility from the Utilities folder and go to partitions, do you see just one partition? Be careful while in DU as not to damage anything.

My recommendation is to download Sierra and create a bootable USB installer. You will need an 8gb (or larger) USB/Flash/Thumb drive for this. After you download Sierra, make a complete backup of all files you need saved.

After you make the USB installer, restart the MBP and hold "option" to get to the boot options screen. You want to start up from the USB, so select that. You want to get into Disk Utility to erase and partition the drive. In the sidebar, you will see the connected volumes and disks. Select the upper most volume, and select Erase.

After the disk has been erased, you can start with the installation of Sierra, by quitting out of Disk Utility.

So pretty much download a seperate version of Sierra to the USB (I have a 16gb one) then follow the steps after the first link you put in? I have nothing to back-up thankfully

See this link, https://support.apple.com/en-us/HT204904, look for the section about "erasing startup disk".
