I tried with a Windows 10 iso that was free from microsoft the error messeage read "Boot Camp only supports 64-bit Windows installations on this platform. Please use a ISO file for 64-bit Windows installation." I especially made sure that I got the 64-bit version. Is there any problems with what I did or is there any solution to the problem. Please help I am hopeless with the apple OS X system thanks
You downloaded an ISO which contains both 32-bit and 64-bit W10. Use your Product key to download a 64-bit only version. You should first in-place upgrade W7/8+ on your Mac which registers it with Microsoft. This will allow you unlimited re-installations on the same Mac.

Nov 9, 2015 5:57 PM in response to omingokeby Loner T,1. If your ISO contains any single file larger than 4GB, it will not be copied to the USB.
2. If the USB is USB3, this error can happen, but is inconsistent across brands of USBs.
3. Changing the DMG to .iso and back is not going to make a difference.
4. Did this ISO come from Microsoft download?

Well, yes, my ISO files are larger than 4G
2. If the USB is USB3, this error can happen, but is inconsistent across brands of USBs.
Nope, my USB is not USB3, its USB2
3. Changing the DMG to .iso and back is not going to make a difference.
Got it.
4. Did this ISO come from Microsoft download?
Nope, I'm making the ISO file from disk installer.
What do you think? Where have I gone wrong?

Nov 9, 2015 6:25 PM in response to omingokeby Loner T,As a test, can you download W7 from https://www.microsoft.com/en-us/software-download/home and try to create the USB, using the first two options in BC Assistant? We do not need to install anything yet. Please be aware that the Microsoft download can be corrupted over a wireless connection. Use a wired connection, if possible.

Nov 25, 2015 7:56 PM in response to RA_Mac_Book_Userby mikethemartian,I am trying to install Windows 10 Enterprise using Boot Camp but I also keep getting the error "Your bootable USB drive could not be created"
I have a late 2012 Mac Mini with Yosemite.
The IT department at my company gave me the standard setup.exe and other files and folders on a flashdrive. I used Mac Disk Utility to create an ISO file from this which I have saved in my main Mac drive. When I use Boot Camp I select the ISO file and my destination disk which is a 32GB SanDisk Cruzer flashdrive which I have already formatted for MS-DOS FAT using Disk Utility. When I start the process the ISO file appears in Disk Utility so I first "Eject" it and then "Remove" it. However it keeps remounting. I get to the prompt "The drive will be erased.". This is my last chance to eject and remove the ISO file in Disk Utility which I do before continuing. The volume gets formatted and then begins to "Copying Windows Files" after which I get the "Your bootable USB drive could not be created" error. The end result is a volume named "WININSTALL" with only one file "autorun.inf"
Is there a way to prevent the ISO file from being remounted?

Nov 26, 2015 5:39 AM in response to mikethemartianby Loner T,1. Is the USB from your IT Department still connected to your Mac when you try to create the USB installer on the 32GB SanDisk flash drive?
2. Can you move the ISO to your Documents folder rather then leaving it on your Desktop?
3. Is the 32Gb SanDisk a MBR scheme device or a GPT with a FAT partition on it? You can also post the output of Terminal diskutil list command with your USBs connected.

Nov 27, 2015 12:17 PM in response to Loner Tby mikethemartian,Loner T thanks for following up with me
1. Is the USB from your IT Department still connected to your Mac when you try to create the USB installer on the 32GB SanDisk flash drive?
I only borrowed the flash drive long enough to copy the files over to the Mac main drive. I didn't have it when I tried to install via Boot Camp.
2. Can you move the ISO to your Documents folder rather then leaving it on your Desktop?
I moved the ISO to both the Documents and Downloads folders but get the same error.
3. Is the 32Gb SanDisk a MBR scheme device or a GPT with a FAT partition on it?
When I partition the flashdrive using Disk Utility I choose the option "Master Boot Record"
I should add that I also have Parallels 10.3. When I try to create a virtual installation Parallels has no problem recognizing that it is a Windows 10 ISO, but I eventually get an error that "No boot device is available". I don't know if that may give a clue.
You can also post the output of Terminal diskutil list command with your USBs connected.

Nov 27, 2015 12:27 PM in response to mikethemartianby Loner T,1. You should disconnect all storage that is not needed for Windows installation. Only the USB Installer (SanDisk) and the internal disk on Mini should be connected.
2. Is disk6 your ISO?
3. Your USB seems to be correctly formatted.
4. We can manually create a USB Installer, if necessary. Do you want to try this method?
