I have a 2017 iMac 27" with a 3tb fusion drive and my external storage is a 500GB Samsung X5. I have successfully installed boot camp on my iMac, ran all boot camp drivers, and then updated windows 10 pro. From there I created an image of my boot camp volume with Winclone 8.1. I then restored the image to my Samsung X5. I shut down my Mac, booted to startup manager and chose the X5. Then pops up the windows logo and the spinning circle on the screen. Eventually the screen goes to black but if I move the mouse I can see the cursor.I have tested this with legacy startup and it doesn’t recognize the startup drive. I only get the option to boot to the X5 with a EFI boot.
Is there something I am missing here? What recommendations or information do you need?
