Q: windows 10 not recognised as being higher than 7

I have an iMac Retina.

I'm trying to bootcamp Windows 10. Bootcamp Assistant does not recognise it as being a higher version than 7. It says it can't find an installer while there is a bootable USB stick there made from my Windows 10 installer DVD. There is also an ISO on the desktop.

 

I had to make the bootable installer disk in bash using dd, because Disk Util and Bootcamp Assistant kept throwing errors when I attempted to make the stick using them and the installed ISO that I downloaded from Microsoft's site, as per Apple's instructions. I keep finding help and advise that tells me these issues won't occur, so presumeably some people actually manage to do this without all the pain I'm experiencing. If those who have also had trouble could share their solutions that would be awesome

    Remove all external disks, other than your USB2 flash drive. The W10 ISO should not be mounted.

     

    Please run the following two procedures, before your next W10 installation attempt.

     

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

    How to Reset NVRAM on your Mac - Apple Support

     

    If you downloaded the W10 ISO over a wireless connection, verify the size and MD5sum of the ISO.

     

    ls -lgh Win10_1607_English_x64.iso

    -rw-r--r--@ 1 staff   4.1G Jul 17 17:28 Win10_1607_English_x64.iso

    openssl md5 Win10_1607_English_x64.iso

    MD5(Win10_1607_English_x64.iso)= 88b98698600511dcd69596df92b242e5

    If you are using a different ISO, post the name of the file and the MD5sum.

    Thanks Loner. I've actually got past this point now. Using dd to set up the thumb drive made it suddenly (and magically) possible for this process to move forwards to the point where it partitions. It now fails there.

     

    I have however done as you said (SMC and NVRAM), and it's the right iso. Now it gets about 30 % of the way into the partitioning of my system drive (50-50) and stalls just saying an error occurred while partitioning my disk. My disk is 75 % empty.

    In Applications -> Utilities -> Console logs, look for any disk-related messages.

    This is a problem. Did you disconnect all external drives, except the USB used by BCA to create the Installer?

     

    I suggest booting into Internet Recovery and running

     

    diskutil repairDisk disk0

     

    Do you have a Fusion drive? Please post the output of

     

    diskutil list

    diskutil cs list

     

    from OS X Terminal.

     

    Also, can you provide details of what was dd'd to the USB?

    I dded Windows 10 Home 64 bit installer DVD purchased from my supplier, but BA didn't recognise it. It did however suddenly succeed with the downloaded iso Win10_1607_English_x64.iso, which kept failing with the Win7 and above error before that.

     

    I'll try the diskutil repair now.

    Internet recovery mode is giving me hassles now. It's just sitting on the wifi selection screen. Have authenticated on the house wifi, and have connection via ethernet, which it is ignoring. Won't take next step. What does internet recovery mode bring to the party that basic recovery mode lacks?

    BA will not recognize a mixed (32-bit/64-bit) installer, or, an ISO equivalent on a USB. On UEFI Macs, the installer will start using the USB created using dd, if you pick the EFI Boot icon from the USB.

     

    The Win10 ISO you downloaded is the correct ISO. BCA takes parts of the ISO and adds Windows pre-boot drivers and structures to allow a proper boot from the USB installer.

    IR should prefer the ethernet over WiFi. If you do not enter a password/do not authenticate, do you get to a Recovery Console?

    Your Recovery HD is local, while IR boots using Netboot from Apple servers. There are some cases (open files), where Recovery HD being in use, does not help the repairDisk process. IR does not use local Recovery HD.

    Good to know! Thanks for your help. Did repairs in recovery mode, sans Internet and partitioning is now past 75 %, so that's a good sign. I'm dubious, as with every roadblock removal a new one fires up, but this is another hurdle dealt with, thanks to you

    Posting from Windows 10! Thank you for all your help, Loner T. I also learned about the console, which I hadn't come across before, and which will be jolly handy in future.
