I am using Boot Camp to install Win7Pro64 OEM on a iMac5K. I get the following message and can not continue. "Your bootable USB drive could not be created. Boot Camp only supports Windows 7 or later installation on this platform. Please use an ISO file for Windows 7 or later installation." Please help.
iMac (Retina 5K, 27-inch, Late 2014), OS X Yosemite (10.10.1)

Which versions of Windows work with Boot Camp 5.1?
Boot Camp 5.1 supports 64-bit, non-Enterprise versions of Windows 7, Windows 8.0, and Windows 8.1. This version of Boot Camp doesn't support Windows XP, Windows Vista, or any 32-bit version of Windows. Depending on your Mac, you may be able to use an earlier version of Boot Camp to work with other versions of Windows. For details, see the Boot Camp system requirements for Microsoft Windows.
I am trying to install Windows 7 Pro 64. Everything I read says that version is OK.
Can you test with a retail or volume version of Windows 7, instead of an OEM version?
I could if I buy another copy of windows. And it seems like no one can say for sure that is the issue.
OEM versions create problems. You can try with a trial version of W8 or W10, and test if BCA will recognize and use the ISO. You should also look in Console logs for any errors from Bootcamp Assistant.
I have installed OEM versions on macbook air and macbook pro without any problems.
What OS X versions do you have on the MBA and MBP?
Don't recall exactly. Macbook Air was just a few months ago and Air had late operating system available. Macbook Pro was several years ago.
The BC drivers for the iMac5K are ONLY available via BCA and are version 5.1.5766. The BCA has become much more stringent in its checking of usable Windows Media.
From what I can tell, there is nothing wrong or illegal about using OEM versions. Just no support and not transferable to another motherboard or machine. Windows is so overpriced it's rediculous. So I should try a full retail version? Windows 7 or 8? I am using 7 and it is acceptable. I hear a lot of complaints about windows 8. So what is the deal? Do I have to use bootcamp to install windows? I can't believe I'm the first one to run in to this issue.
Try W8+ (it has better EFI support), and it is possible to install Windows without using the BCA and it's partitioning, using a method called EFI boot, since the iMac5K is UEFI compliant. You should first clean up and delete the BC partition via 'Remove Windows' option before you try the EFI method.
