Windows not bootable

I just bought Winclone 9 - did successfully Volume to Volume clone.

Then when I start macbook with alt and choose EFI boot from external drive it starts booting Windows 10, but after 1min of loading Windows with progress circle it just restarts.

  1. Is it possible at all to boot cloned BOOTCAMP from external drive in macbook? I did that few years ago, but is it still possible?
  2. If not possible, would it be possible with fresh windows installation to boot form external drive?
  3. Is it related to existing BOOTCAMP partition on main SSD of macbook? Should I remove SSD Bootcamp and then try again, would I be able to restore back to SSD if it would fail?

1 2 both are possible
3 i think you did something wrong, but I am not sure
