Q: Win 10 won't boot after install (retina iMac, 3tb fusion drive)

I have spent a frustrating day trying to install win 10 on my 2014 retina iMac (3tb fusion drive)

 

No problems with boot camp and the install from usb key (64bit Windows 10) but the first time that Windows fires up after the install it crashes with the message "Your PC ran into a problem.... Critical process died" and continues in a loop booting to this problem until I option boot to OSX.

 

Tried the install process a number of times from scratch and from a different iso but get the same issue?

 

Wondering if it might be an issue with the fusion drive config?

 

many thanks

    Do you have access to a wired keyboard/mouse you can test the installation with?

    Hi Loner T, tried it with a wired keyboard and made no difference.

     

    I have been looking at the discussion boards and it seems to be quite common and in some cases is fixed by removing the partition via BCA and then trying again. Obviously I can't do this as it was your clever Terminal commands that split my disk. If I ran the command again would it reset the drive or create further partitions? Is there a command to clear the BOOTCAMP partition that you created and recreate it?

     

    This is all quite nuts eh?!

     

    Thanks again for all of your support!

    Updated - Try to remove and recreate the partition. It may not work, because you have a REMAINDER portion. Your partitioning should not be causing the keyboard/mouse issue.

    Yes BCA can't remove the partition.

     

    I don't mind installing Windows 10 first if that will work, anything to get it working will be fine by me.

     

    So what is my best option for blitzing the disk and current partitions?

    We can try to install W10 using EFI Boot.

    Ok but I have failed EFI installs before. So do I repartition the drives during the first stage of booting Win 10 from EFI?

     

    Also, are we saying that we will blitz all partitions, install Win 10 and then introduce a partition after booting from OSX off USB?

     

    Don't want to miss any steps.

     

    Thanks

    The 700Gb can be converted to Free Space and you can point to it and install W10 using EFI Boot, without having to repartition.

    Hi Loner T,

     

    Well I happy to say that my Mac is finally running Windows.

     

    In the end I re-partioned the drives without installing any OS.

     

    Rebooted into the Recovery partition and downloaded OS from the internet (Yosemite).

     

    Ran Bootcamp from Win 7 image downloaded from Microsoft

     

    Downloaded the iMac legacy bootcamp drivers

     

    Installed Windows (which worked)

     

    Upgraded Yosemite to El Cap

     

    Upgraded Win 7 to Win 10

     

    Thanks for all of your help!!!!!! Much appreciated.

     

    Regards

     

    Alex

    Please make good backups of OS X and Windows.
