Bootcamp Cloning to external SSD

Hi,
I can clone my boot camp partition with Windows 10 to my external SSD, but after, I cannot but from the SSD “error loading operating system”
I use winclone 8.2 and macOS 10.15.7
I have test both version
make EFI bootable and legacy bootable - unfortunately both do not work :frowning:

What else can I try, my MacBook Pro is early 2013 .
I want to save my Windows 10 portion because I want to buy a new MacBook soon.

I CAN MOUNT THE SSD AND SEE ALL DATA AS SAID BUT I CAN NOT BOOT.

NEED HELP

KdRgds,
Sylvio
