I made a Windows 7 installation USB using Microsoft’s installation tool on my Windows PC. When I boot the Mac while holding Option. Only the Mac disk appears. The USB is NTFS. I checked if anything is wrong with the USB and nothing seems wrong. I’m not using Bootcamp because it only accepts Windows 10.
Is there any way to get it to appear? I don’t want to install Windows 7 in my Mac OSX disk using Virtual box.
