when need to clone a system disk with Windows 11

 use tool MultiDrive https://multidrive.io/ - it can clone a disk to disk with both on USB or VHDX file to physical drive. 

I used version 1.1.0 2025-07-08 

this will give you a cloned disk that might not boot! 

then follow the guide https://woshub.com/how-to-repair-uefi-bootloader-in-windows-8/

this is by far best guide I have seen to fix the boot of windows 10 or 11
