Windows 7 install on mid 2010 iMac
I installed a new SSD main drive; installing IOS 10.13 on it. I would like to restore my bootcamp partition with my Windows 7pro software. I have a USB 16Gb flashdrive formatted in MS-DOS FAT with the appropriate drivers.
When I insert the original Windows 7 installation DVD I get the message "Windows 10 is not supported on this Mac Please use a DVD or USB drive which contains Windows 7 or Windows 8."
That's as far as I get. Why does it think the DVD is Windows 10? Ideas?
iMac, iOS 10.1, High Sierra v 10.13.4
