I cloned windows 11 to SSD to replace the HDD but it did not boot up despite the clone was successful, why is that and what solution to solve this?

I noted that the portion on the HDD is GPT and on the SSD is MBR?

Can I use the SSD as another booting device and how?

On cloning to the SSD is it better to connect to USB or can be connected internally then cloned?

Thank you.

Any help is very much appreciated.
