Q: Install W8.1 on iMac 21.5 Late-2013 failed

I did try everything to get it work but no success.

 

Started bootcamp and partitionned 200GB on my Fusion Drive.

Bootcamp created my USB with a W8.1 Pro and the drivers.

 

I replaced the driver with BootCamp5.1.5640 as my mac was listed to use this drivers in this KB.

Boot Camp Support Software 5.1.5621

 

No can do, I always get the same error when Windows try to install

A:

OK! Got it working.. finally!

 

Main problem is that I wasn't seeing my fusion drive but I was seeing the SSD AND the Mechanical Drive!

I deleted the partition I created before via Disk Utility, rebooted, started BCA.

Did a new USB with default drivers, partitioned again, downloaded the 5640 and started installation.

 

Once restarted I could only see my Fusion drive AND the BOOTCAMP partition.

 

Installed correctly now.

    1. There is no reason to replace the drivers on a USB created by BC Assistant? Please read both links carefully.

    2. From System requirements to install Windows on your Mac via Boot Camp - Apple Support, your iMac needs

     

    Boot Camp Support Software 5.1.5640 which has

    That's OK. I will not change the drivers when creating the usb via BCA.

     

    But it doesn't answer my question:

     

    • How can I install W8.1 on that iMac!

     

    It user to work without any problem on my mid-2011

     

    In fact this is a new iMac (got it last thursday)

     

    Or If could install at least W7, I would already be happy.

    But this one doesn't work either.
