The only reason I'm posting this is because I was stuck for a few hours and the internet had tons of conflicting fixes for this that led me nowhere. Still stuck with GPT errors and a whole lot of general bollocks. For some reason this refused to work on the USB port on the left of my macbook and for reasons known only to Job's & Gates' lovechild, worked on the one located on the right. Sorcery.
This is what worked for me, I can't guarantee that it will work for you and I'm by no means a Mac expert - so use at your own risk. Caveat emptor. No screenshots because of reasons.
What you need:
1. MacBook or other Mac Computer that is listed here: https://support.apple.com/en-us/HT204990
El Cap seems to have nuked my Bootcamp created Windows 10 partition and it won't let me install one outright. I get the 'This is GPT partition style' error, and I'm not sure how to fix it under El Capitan.

Oct 17, 2016 I have recently installed Windows 10 on my iMac (27-inch, Late 2013.) I have successfully gotten the internet to work, but not the sound. I have upgraded and installed the newest Bootcamp software, but still, nothing. I have watched repeated videos, yet, nothing has happened sound wise. I've tried putting in headphones and that doesn't help.
2. Windows 10 64-bit ISO.
3. A fresh USB stick, 8G or more would be fine.
4. At least 100GB free on your Mac for a 64GB Windows install.
What's next?
0. Update your mac if needed.
1. Run bootcamp and select the two options
- Create a Windows 7 or later setup disk
- Download the latest windows support software from Apple1.1. Click Continue, grab a beer. or three. This takes a while.
2. Exit bootcamp. Because of reasons.
3. Fire up bootcamp and this time select the option to install (only).
4. Drag a partition size that suits you, I went with 64GB - then click Continue
5. Magic happens then the computer would probably reboot right into OSX. Manually reboot and this time hit the Option Key, Feel free to bang away at it. (Disclaimer: Do not bang away at it.)
6. When presented with boot options, please ignore the Windows option. Select UEFI boot.
7. Oh looky, run through the windows install until you get to the Disk screen. At this point choose your desired windows partition created in step 4 and then click format. The next button magically appears and you should now be able to proceed with installation.
8. Magic happens again, then a couple reboots later and Win 10 is done. Grab another beer. or three.
9. The next time you bring up the dual boot screen, Only OSX and Windows would be presented and the UEFI option is gone.
10. Happy dualbooting. Hell you'd be happy too after six beers.

How to install Windows 10 on Mac
To install Windows, use Boot Camp Assistant, which is included with your Mac.
1. Check your Secure Boot setting
Learn how to check your Secure Boot setting. The default Secure Boot setting is Full Security. If you changed it to No Security, change it back to Full Security before installing Windows. After installing Windows, you can use any Secure Boot setting without affecting your ability to start up from Windows.
2. Use Boot Camp Assistant to create a Windows partition
Open Boot Camp Assistant, which is in the Utilities folder of your Applications folder. Follow the on-screen instructions.
- If you're asked to insert a USB drive, plug your USB flash drive into your Mac. Boot Camp Assistant will use it to create a bootable USB drive for Windows installation.
- When Boot Camp Assistant asks you to set the size of the Windows partition, remember the minimum storage-space requirements in the previous section. Set a partition size that meets your needs, because you can't change its size later.
3. Format the Windows (BOOTCAMP) partition
When Boot Camp Assistant finishes, your Mac restarts to the Windows installer. If the installer asks where to install Windows, select the BOOTCAMP partition and click Format. In most cases, the installer selects and formats the BOOTCAMP partition automatically.
4. Install Windows
El Capitan Windows 10 Bootcamp Drivers
Unplug any external devices that aren't necessary during installation. Then click Next and follow the onscreen instructions to begin installing Windows.
5. Use the Boot Camp installer in Windows
After Windows installation completes, your Mac starts up in Windows and opens a ”Welcome to the Boot Camp installer” window. Follow the onscreen instructions to install Boot Camp and Windows support software (drivers). You will be asked to restart when done.
- If the Boot Camp installer never opens, open the Boot Camp installer manually and use it to complete Boot Camp installation.
- If you have an external display connected to a Thunderbolt 3 port on your Mac, the display will be blank (black, grey or blue) for up to 2 minutes during installation.
How to switch between Windows and macOS
