Successful install of Windows 10 onto mid 2007 iMac

I was delighted to find out, that I could successfully install windows 10 onto my older 24 inch mid 2007 iMac with 4 GB RAM.

Steps involved:

1. I installed a new 3 TB superfast internal hard drive

2. El Capitan was successfully downloaded and installed on to this 2007 iMac.

3. The most recent version of bootcamp which came with El Capitan, was then installed and the hard drive partitioned equally between the Mac and Windows interface.

4. Using a Windows 7 Pro upgrade disk, was able to get Windows 7 Pro installed on the Windows partition. Because it was a new install with an upgrade disk, had to call Microsoft to help with the activation process and they reset my code.

5. Once Windows 7 Pro was activated and running properly, was able to successfully download and install Windows 10 Pro on to the iMac system. The windows 10 installation stalled a couple of times while gathering updates, and this was defeated by turning off the Windows update service via the command window (net stop wuauserv).

Windows 10 is now running flawlessly, the iMac is been set up so it boots via boot camp directly into Windows running on top of my older macintosh hardware. If I can get a couple of years out of the system, I will be happy.

Now I plan on doing the same with my wife's 20 inch 2006 iMac.
