Why doesn't my cloned hard drive boot?

I have a 500 GB SSD hard drive in my laptop and wanted to clone the SSD to an external USB 500 GB hard drive using Paragon.

There are 4 partitions on the SSD. The 1st is LW () with the MBR and status ACTIV, the 2nd LWC system, the 3rd LWE data and the 4th LW () unnamed. Anything with recovery data on it.

After cloning, the contents of the partitions on the target drive are identical, but the drive letters are no longer there or changed.

It somehow makes sense to me that in the original the path details C: \ harmonize with LWC, but if the target drive is no longer C: the path details are no longer conclusive. Do I have a mistake somewhere and how can I make the cloned hard disk bootable? Will soon be 76 and am no longer the fittest, but grateful for every good tip.

Let's make it short:

If this is a system hard drive, it can't work at all.

Cloning is only meant for two things these days:

System disk backup

Cloning the data on a disk that does not boot.

And no matter how many people will report to my post now and also brazenly think that I have no idea, they should be told: this is about the subtleties that are not considered and not about the "blunt" 1: 1 Copy.

Briefly summarized:

In Windows, you can no longer easily clone a hard drive partition (which is also a system partition) to another hard drive on the same computer.

Too many variables that do not consider such partition programs.
