How to install Windows 10 on Mid 2010 iMac 27"- i3 core with Boot Camp

I am trying to install Windows 10 on my Mid 2010 iMac 27" El Capitan (Version 10.11.6), with 3.2GHz Intel i3 Core. I followed the steps using Bootcamp , and a 16 GB USB flash drive, it stops after downloading the Windows support - and a message comes up saying that no installation disk is found. the process stops and Bootcamp complains of absence of the installation disk. I have Windows 10 ISO file downloaded as well on my desktop- How to get out of this hole? I see many videos on installing windows 10 successfully, buy mine in 2010, and it seems problematic at this juncture. Any help is appreciated. Thank you

Your 2010 iMac has two options in BC Assistant UI. Download and Install.


  • Download only downloads Windows Support Software for W7/W8.1 on your model. There are no W10 Apple-certified drivers.
  • Install needs a DVD Installer, which can be created from the ISO you have.
  • Apple does not support a clean installation of W10 on your model. However, if you install W7/W8.1, then an in-place upgrade is possible.
  • You can clean install W10 via DVD (in BIOS mode), but will need to rely on the standard WHQL drivers, instead of Apple Bootcamp drivers.
