Windows 8.1 Pro

I have a USB key with Windows and Apple tools installed. Bootcamp did a fantastic job on formatting the USB key and priming everything for install. In the next step, when I attempt to create a partition for Windows 8.1 pro (using Bootcamp) two things occur. 1. The 'Divide Equally' button is grayed out. 2. After manually selecting my disk partition size, I receive a 'Your disk could not be partitioned error' about 30 seconds after hitting the install button.

I have had no luck installing bootcamp Windows 8 or Windows 10 on my late 2015 iMac. The first time I tried with Windows 8 and got Apple support involved resulted in the iMac getting returned. Apple support completely screwed up the main partition and could not return it to its original size. Aug 18, 2015 Aug 18, 2015. One serious bug should be considered when trying to do this. El Capitan boot camp assistant will fail to remove your Windows partition if you don't want that Windows installation. And you will likely end up with backing up your Mac OS X and format the whole disk to bring everything back to normal. The first time you open Windows 10 on your Mac, a window will automatically appear for installing the Boot Camp download onto your Windows 10 partition. This is a critical step; it downloads drivers and software necessary to maximize your Windows 10 experience on Mac, and allows for seamless switching between the two platforms.

Included is a screenshot of the event log. The action occurs from 9:30-9:31. Thank you for your help. Cheers!

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.

1.1. 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.
