1. Uninstall the current windows partition with Boot Camp Assistant

2. Run Boot Camp Assistant to create the install disk (uncheck “Install Windows 7 or Later”; only create the install disk)

a. Use a Windows 7 64 bit ISO file and a flash drive, follow instructions on screen

3. Download the correct drivers from Apple’s website

a. https://support.apple.com/en-gb/HT205016

b. Download the drivers for Mac Mini (Late 2014, or whatever model you have)

4. On your USB stick where you have just created your Windows boot disk viaBootcampAssistant:

a. find the $WinPEDriver$ andBootcampfolders and delete them. Replace them with the folders from theBootcampfolder you downloaded in step 3 above”

5. Run Boot Camp Assistant and install Windows 7 from the flash drive. Make sure the “Install Windows 7 or Later” box is the only checked box.
