Q: Problem with Win 7 installation on El Capitan

I've got iMac 27' mid 2010, OSX 10.11.6.

I had Win 7 installed, but I decided to enlarge the bootcamp size. So I deleted the partition via BCA and tried to re-install Win 7.

The problem is that my optical drive is dead. So I tired to use the external drive. BCA allows me to create the partition and download drivers, but after the restart I see "no bootable device found; insert one and press any key" error.

I used burned iso (from MS site) and the original Win 7 disk, however the result is the same.

The only way I see is to downgrade to Mountain Lion and install Win 7. Then upgrade again to EC.

"What happens if you put in an Audio CD?" Nothing, it eject in 10 sec after
"did you get a chance to look" Yes, but I have no problem with eject since no disk able to mount. Nor CD, neither DVD

2012-2014 support USB Installers, irrespective of the built-in Optical drive. For example, I have a 2012 13-in MBP, which supports both USB and DVD installation.

Do you have any third-party software which can control CD/DVD drive?

"13-in MBP" I'be experienced no problem with MBPs, this issue is in respect of iMac only.
"Do you have any third-party software which can control CD/DVD drive?" No.

If you have an external optical drive, can you use the drutil command and test it on the external disk.
