It is not needed for you to upgrade your wife's iMac - only download the Sierra install app. When it automatically launches, select your USB connected external drive to install Sierra on. When installation on the USB connected drive is complete, hold the optio key while rebooting and select the USB drive to boot. If it boots OK, then you have a viable drive for your PCMac build. All you need then is to install it in your PC, boot with a USB drive with Clover installed on it and install files with MultiBeast.GB:
Thanks for the information. However, there may be a glitch.
You said: "...download the install Sierra app, run it pointed at the USB connected drive and install to the external drive. Reboot to that drive to make sure it is a viable installation. If it is working, while you are there, download the app to your drive, create a UniBeast USB installer for booting your PCMac with, shutdown and move the drive to your build." I don't know if my wife wants to upgrade to Sierra at this point and it isn't my call anyway. After the boot to the USB device for verification, I assume that the hard drive would remain unchanged and the iMac would boot into El Capitan. Further, I assume that completing the USB device would be done under El Capitan.
Easiest way to create to boot USB is with UniBeast. I am not sure if installing to an external drive will delete the Sierra app from the iMac's app folder. If it does not, simply copy it to your external drive app folder and delete it from the iMac.
Create it from the Sierra drive connected via USB once you have booted it and have the Sierra install app in the app folder.If that isn't the case, it there a Plan B? Finally, on my agenda is setting up a dual boot and installing a PCIe WiFi card. Would it be better to do these things now or after Sierra is installed?
Or, you can ignore all that to create a UniBeast USB and create a boot USB by following https://www.tonymacx86.com/threads/test-drive-how-to-create-a-clover-usb.127134/
