Has anyone successfully installed Windows 10 on an iMac 4K with bootcamp?

I keep getting an error when I try to install Windows 10 home 64bit on my iMac 4k using Bootcamp. I get as far as selecting the Bootcamp partition, formatting it and then when I select the partition to install Win10 I get an error that it can't be installed. I tried this several times and get the same error at the same point.

I thought that was something due in IOS 9?

No, Botcamp has been updated to support Win10 but it's not working for me. I had difficulty getting Win10 loaded as well before Win10. I'm ready to chuck this whole thing and get a new AIO Windows Computer!
