Boot Camp Assistant problems

I am trying to install Windows 10 on my 2015 MacBook Pro 13.3" running Mac OS X El Capitan (10.11.2) but I am unsuccessful (for software that is not supported by Mac OS X). I have tried several times but it always says that my disk space is not enough (cannot remember the exact words in the error message). I then opened the Boot Camp Assistant through the terminal and saw that it only recognizes that the drive would have 4GB of free space available (I have a 500 GB SSD and 130 GB is used) but some insane amount of about 140000000000000 GB was used (what?). When I check in the Disk Utility I also get some suspicions that Boot Camp Assistant selects the Macintosh HD partition, instead the the actual drive. In the Boot Camp Assistant I can choose the size of the partition (I want to leave 370 GB for OS X in the Macintosh HD partition and get 128 GB for the Boot Camp / Windows 10 partition). I can't get this to work and I am grateful for any help!

MacBook Pro with Retina display, OS X El Capitan (10.11.2)

The MD5 for my ISO is: MD5 (WINDOWS10.iso) = 538041b21eeb458bed03ee787309903c

That ISO was >15GB, the one I downloaded from Microsoft was <4GB.

But thank you very much! I finally got it working. The Boot Camp drivers on Windows is however struggling to install. It is stuck on Realtek (google revealed I am not the only one with that problem). So I stopped it and now I can't find a way to restart it.

Please see Bootcamp 6.0 driver install interrupted to address the installer issue. You can manually download the BC drivers using BC Assistant.

Thank you. Had some trouble saving it, but I managed to solve it. It stopped at Realtek again, but then I did as someone else had and removed it from the Drivers folder and re-ran the installation. Then I manually installed Realtek.

And now it all works. Thanks a lot for the help 🙂
