Q: Boot Camp only supports 64-bit windows installation. Trying to Install windows 10

Im using my 15" Macbook pro from late 2014. Everything is completely up to date in the app store, and bootcamp isn't recognizing the windows 10 64-bit iso files that I have. All the support I have found on the subject was for people who bought the usb that came with both the 32 and 64 bits, but I downloaded mine straight from the windows website and only have the 64-bit versions.

MacBook Pro with Retina display, OS X El Capitan (10.11.1)

    1. What is the size of the downloaded file?

    2. From OSX Terminal Window, run the highlighted command in the directory where the ISO is located and post the output or check if it matches the value shown.

     

    openssl md5 Win10_1511_English_x64.iso

    MD5(Win10_1511_English_x64.iso)= a0d4271b7537732a060909fd39d54829

    After I enter the Command into the terminal (copy+pasted so I didn't mistype) it tells me no such file is found though I am staring at the file right in front of me. I checked to make sure file name was the same and Win10_1511_English_x64.iso is definitely the name of the file. Does this mean my computer is unable to recognize the existence of this file? I also tried pre and post mounting, don't know if that would have any affect, but I tried it anyway.

    In your OSX Terminal window, type

    cd ~/Desktop

    openssl md5 Win10_1511_English_x64.iso

    I have seen issues with the ISO file on the desktop. Move it to your Document folder and do not open it. Once it is in Documents, run BC Assistant.

    Alright, I have now confirmed that the values do match, but after moving the file into documents and running bootcamp, I get the "only supports windows 7 or higher" message. Is it possible the destination disk is the problem? I was using a cheap usb drive that had nothing important on it because bc told me to plug in a usb. I didnt realize at the time that the destination disk was that usb until today when I plugged in an external harddrive that was given to me and that became the new destination disk. The problem still persists though, even though I have installed the mac drivers to allow me to write data onto the drive.

     

    If its possible, I would like to make the ext harddrive a bootable windows drive, but being able to boot windows at all should be priority.

    An external HDD causes problems during Windows installation, and may result in black screens. The safer approach is to find a better non-Generic USB2 flash drive.

     

    Can you also run a SMC and NVRAM reset and retry BCA with W10? Leave the ISO unmounted.
