Cannot install Windows on Bootcamp after replacing 3TB FusionDrive with 1TB SSD

3TB Fusion Drive was replaced by 1TB SSD drive. When reinstalling OS X i see that the 128GB of Fusion drive is still available as a harddrive, stopping me from installing OS X or Windows (Bootcamp) on the SSD.


I've been testing quite a few ways of installing:


  1. OSX on SSD (Internet Recovery Mode, deleting all partitions and repartitioning SSD)
    The installation fails when trying to install
  2. OSX on FusionDrive (128GB), Bootcamp on SSD
    OSX installs fine, Bootcamp does not. First time (Windows 10) i got an error message with I/O failure and winload.exe, second time (Windows 8.1) a dos message with "Failed to load operating system, press CTRL+ALT+DELETE". Done this part a few times.
  3. OSX on FusionDrive (128GB), Bootcamp on the same drive
    Working, but limited to 128GB for both OSX and Bootcamp
  4. Making Logical Volume (fusiondrive) with both 128GB and 1TB
    OSX Working, but cannot give me more than 64GB to my Bootcamp. Bootcamp at 64GB ok.
  5. OSX on FusionDrive (128GB), Bootcamp on FusionDrive - moving to SSD with Winclone
    Clean Windows 8.1 install, sysprepped. Everything seems ok in Winclone. When trying to restart i get a message similar to "failed to load operating system


I would like at least 800GB on my Bootcamp. Does anyone know how to make this work?

No backup necessary, using Internet Recovery mode to reinstall.

What now?

One step closer, but still not quite there.. For the first time i get to choose how much diskpace i want to align to my bootcamp partition. When i press install the OSX starts partitioning. When the status-bar hits 100% i get the message (translated from Norwegian) "The disk could not be partitioned. An error occured during partitioning of the drive."


I've downloaded all updates in app store. Should i Upgrade to El Capitan?
