I have been following this answer to install Windows in Boot Camp.

Seemed to work absolutely fine until the command e:\setup in step 9. When this command is run "The subsystem needed to support the image type is not present." is returned.

setup.exe is available in the directory though.

I'm unsure on how to proceed from here, as it has been some years since I last fiddled under the hood of a windows product.

Any help is highly appreciated.


Worked out what the issue was. Double checked the specs of my machine and realised it was a mid 2007 model. Upon checking with Apple using the link in the linked answer I found the specific bootcamp file and that I had to use Win 7 32bit. Altering these files and using the correct disk image allows the installation to start.

Thanks for your help David.


  • You may be correct, but the funny thing is I created and tested the procedure to install 64 bit Windows 7 Pro using a 20 inch, mid 2007 iMac. Apple reports that my machine must install the 32 bit version of Windows, but I have been able to install the 64 bit version of Windows 7, 8, 8.1 and 10. If you are using the same "Boot Camp Support Software" (Version 4.0.4033) that I am, then I can tell you that this software is not used until step 10. On the other hand, our machines are different, so just because I can install 64 bit Windows does not guarantee you can. – David Anderson Mar 10 '16 at 10:46

I tried to reproduce the error you reported to have. I could not. If you feel you have not made a mistake somewhere, I would recommend trying to install Windows using the previous method given here.
