Having trouble installing Windows 10 on a mid 2010 iMac

[mozzatron]

Hi all

I gave my son my old iMac for Christmas (27" mid 2010, 2.8Ghz Intel Core i5, 16GB DDR3 RAM, ATI Radeon HD 5750 1024 MB running El Capitan 10.11.6).

He will mostly use it for playing games downloaded through Steam, and a few of the ones he wants to play are only Windows compatible.

I've tried to install Windows 10 via Bootcamp, but i'm really struggling to find any information online which guides me through the process. As it's an older Mac, it seems to be a much more convoluted process (some videos mentioned replacing a graphics card, other mentioned having to install windows 7 first, then upgrading to windows 10).

I though i would come on here to see if anyone can shed some light as it's giving me a major headache!

TIA

Forget about installing W7 and trying to upgrade to W10: I tried that on my 2010 MacPro last fall because I had broken the existing installation. It turns out that you can install W7, but you won't get any updates. The certificate to be able to access the Windows update servers was revoked quite some time ago and you no longer can download the necessary updates directly from Microsoft any more because W7 is out of regular maintenance. So you'll be stuck on a severly outdated W7. Also you cannot use the W7 activation key to activate a W10 installation.

Installing Windows 10 with Bootcamp is a pretty simple process if there were enough free space on this Mac.

First, back up the data on your Mac and download Windows 10 ISO from Mac. Then launch bootcamp app and download Windows Support Software on a USB flash drive in case there are drive issues after install.

Finally, follow the screen prompts to install Windows 11 on your Mac.
