Q: Windows 10 installer stalls

I'm having trouble installing Windows 10 on my new iMac (late 2015 27" 5k). I purchased and downloaded a copy of Windows 10 from Microsoft. I followed ALL of Apple's steps on using BootCamp Utility and the process stops as Windows itself is configuring the installation. It reports: "we couldn't create a new partition or locate an existing one…" However, the Windows installation screen clearly shows the 130Gb partition ( the partition I'd had BootCamp Utility create from my Mac's internal drive) which Windows had just reformatted one step previously. I'm at a loss. I've tried this two times and the same nonsensical response pops up and I'm stuck. Now what do I do?

iMac, OS X El Capitan (10.11.1), iMac late 2015 27"

Please ensure you have a good backup strategy in place for OS X and Windows. Use separate external backup disks for the two OSes, if possible.

Thanks. I already have a Time Machine backup, daily Super Duper clone and Backblaze cloud backup for the Mac side of things. The Windows side is really only used for gaming, so losing data there won't be a biggie. Nothing of importance is, or will be stored there. If a Windows problem occurs, I could simply reinstall the games and/or OS, maybe restore a preferences file as needed from Backblaze, and move on.
