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

    1. Run Disk Utility Repair and re-try BC Assistant.

    2. Boot in Safe  Mode (Try safe mode if your Mac doesn't finish starting up - Apple Support) and boot normally and retry BC Assistant.

    3. Using Disk Utility to verify or repair disks - Apple Support and retry BCA.

     

    If neither of these work, it may require a bit more invasive surgery on tech Mac.

    Have you found a working solution? I´ve exactly the same problem. Windows 10 hangs up when installing the Boot Camp drivers in Windows (iMac 27" 5K, SSD only, late 2015).

     

    Thanks for your help in advance!

    I have the same problem. Tried to install 4 times and the installation process runs fine all the way and windows 10 boot up.

    After 30 sec or so the screen goes totally black and I can't do anything.

     

    One time it went totally black when installing the bootcamp drivers after Windows 10 was booted.

    The other time I waited to install the drivers and after 30 sec. it went black.

     

    Seems like windows is doing something with the screen resolutions ore the drivers ore something. It's very strange.

     

    Any help to get this working will be appreciated.

    Same problem here.

     

    OS X El Capitan 10.11.1

    iMac 5k, 27", late 2015

    AMD Radeon R9 M380 2048 MB

     

    No problem with Windows 7 or Windows 8.1, but when upgrading to Windows 10 everything went black. Also tried fresh Windows 10 instead update from 8.1, same result. Everything goes black after install is finished...

     

    Any solution or dates in which this device will be supported by bootcamp (as it is not in the supported list).

     

    Thanks!

    @JuergenW15, acebeam and pestevan ...

     

    I haven't found a workaround yet.  You're all having the same exact issue I'm having with Windows 10 on the Late 2015 iMac Retina 5K.  I did some research and it looked to be around 2-4 weeks post release of the Mid 2015 iMac Retina 5K when the video drivers and bootcamp was updated.

     

    Everything looks to point to the video drivers, but I've read some blogs saying bootcamp was also to blame after the last update to the iMac.

     

    So I'm just hoping that Apple, Microsoft and AMD are all working on an update right now and that it'll be released in the next couple weeks.  I'm going to try to go into an Apple store and see if their techs have anything to share.  Apple support online and Microsoft support both were not helpful.

    I couldn't even get that far trying to install Windows 10 on my Late 2015 21.5" 4K iMac.

     

    On the 1st attempt it failed to install to the BOOTCAMP partition, even though I formatted it to NTFS as instructed.

     

    On the 2nd and 3rd attempts BCA wouldn't even download the software in OS X.

    If W7/W8.1 installs correctly on a iMac5K 2015, but W10 does not, why are BC6 drivers considered the culprit? The failures during installation point to the generic driver used before BC drivers are installed. For both W8 and W10, the exact identical set of drivers are downloaded from Apple, because BCA downloads drivers which are Mac-specific.

     

    You can verify this on your own, by looking at Bootcamp.xml when installing W8.1 or W10. The MD5/SHA1 can also be verified, if necessary.

    I don't know that the BC6 drivers are the culprit or not.  It just seems that there are people from this thread and others having consistent trouble with BC.

     

    It is more likely the VC drivers being the culprit.  BC worked fine for me (over 8 times now) and I agree that the generic drivers seem to work perfectly. I get all the way to the last step when Windows 10 is booting up (I even see the spinning timer on the screen) and then a flash of Windows 10 before it all goes black.

     

    If you have any help for that ... it would be much appreciated.

     

    @mattdodd ... I'd restore your original partition via bootcamp (i.e. - remove the Windows), shutdown the mac completely, turn it back on, make sure all applications are closed and then start bootcamp again.  I did hit one snag on my second attempt that sounded similar to what you hit.  If you're able to install Windows 10 afterwards and get it working ... please let me know.

    When the screen goes black, is your keyboard and mouse functional? Can you connect an external monitor as a test?

    1. Are there any external storage devices connected?

    2. Is your USB flash drive with USB installer a USB3 device?

    Hi,

     

    In my case, no external storage. Installation is finished successfully. Just when install finishes (being fast enough after install I even could login), screen blinks (honestly like when a screen driver is changed) and never comes back from black when starting on Windows partition, no mouse, keyboard... I don't have a second monitor BTW.

     

    I will wait until some success reports on same configuration with windows 10 as I need to keep working on win 8.1.

    I also have no external storage and no USB drive.

     

    The Windows installation also finishes successfully. But when the Boot Camp installer (after the 1st login to Windows) starts and installs the drivers, the screens goes black and the system hangs up completely. No keyboard/mouse any more. After taking off the power and rebooting the system Windows hangs up again when it should switch to the high screen resolution at the end of the boot process. Only booting in secure mode is possible. I think the display driver is the problem....

    Windows 10 is using the incorrect display driver.

    If the failure points to the generic driver, does that mean your advice in my own thread to use the generic driver before later manually installing the BC driver is unlikely to work?

     

     

    Where is Bootcamp.xml?

     

    Verify the MD5/SHA1 of what against what?
