Q: When will Windows 10 be supported on the new iMac Retina 5K Late 2015 model?

When will Windows 10 be supported on the new iMac Retina 5K Late 2015 model?  I tried installing and it gets all the way through the install and then I get a black screen right as it gets to the part where the UI should present.  It seems like maybe the discrete AMD video is causing an issue or is not supported yet?

iMac with Retina 5K display, OS X El Capitan (10.11.1), Windows 10

FYI to everyone ... I checked the Apple support site yesterday and low and behold the iMac Retina 5K (Late 2015) model now shows up on the list of supported for Windows 10.

 

I tried the Boot Camp assistant again tonight and Windows 10 installed just fine.  So they must've updated the driver support for the new AMD graphics. 

 

Everything is working fine now.

 

Thanks

    It was supported as of a couple weeks ago when updated Boot Camp software was released.

    The website still doesn't list the Late 2015 model that has the 6th gen processors and the newest AMD Radeon M3XX video.

     

    I've tried installing Windows 10 cleanly at least 5 times now with boot camp and and soon as Windows gets to the part where the UI should take over (versus the install utility screens), it all goes blank even though it looks like it's going.

    Are you using EFI Boot manually to install W10?

    I would say no since I'm not sure what EFI Boot is ... I'm using Boot Camp and letting it lead me through the process.  I downloaded the ISO file from Microsoft, I partitioned the disk to allocate 125GB to the partition and then I format the new partition to NTSF.  It gets through the install process, reboots several times and then it asks me to enter my email & phone number ... then I get a spinner (like a wait screen) for a few seconds before the screen goes black and nothing happens.

    It seems to be a GPU driver issue. Can you run the following two procedures and test?

     

    Resetting the System Management Controller (SMC) on your Mac - Apple Support

    How to Reset NVRAM on your Mac - Apple Support

     

     

    Can you also post the exact GPU from the OSX side from System Report -> Graphics/Displays?

    I have the same issue. Windows 10 Installs successfully, then when I try and install the bootcamp drivers, it goes to a blank black screen. I can force a restart, but then Windows just offers to install the bad boot camp drivers again.

     

    Honestly, all I really want is the boot camp control panel, as Windows installs pretty much all of the rest of the drivers I need. Anyone know how to just install bootcamp control panel?

    Can you boot Windows in Safe Mode? If not, remove Windows, and remove the AMD directory from the Drivers folder and re-install Windows.

    What do these two procedures do?  Since it's a brand new iMac ... seems odd to have to reset anything.  Only had it a few days.  Below is the GPU information.

    The SMC Reset rebuilds the internal hardware information. The NVRAM reset will clean state variables for various states, for example, the Windows installation states across reboots.

     

    Install Windows with generic W10 drivers and then test drivers one by one.

    Copy the ISO to your Documents folder. Remove all external storage and retry the installation.

    This is what I did first...copying to the USB drive was the latest thing I tried.

     

    Here are a couple screen shots:

    On the newer Macs, you can either use a USB or run an EFI-baed installation without a USB. Please see https://help.apple.com/bootcamp/assistant/6.0/#/bcmp712cfeb8 for details.

     

    Are you creating a USB Installer?

    I already followed the instructions by taking the Windows 10 CD disc and making an .ISO and placed it onto my Sandisk USB 2.0 flash drive.

     

    Yes, using USB installer that I made by doing above what I just wrote.

     

    I guess I perhaps should say that on the very first attempt before this problem I did get to the actual partitioning part and then the progress bar just sat there at about the 1/4 part and then I quit the installation because I thought that after 30mins it must have gotten stuck.  Not sure if this mucked anything up or not.
