This is an FAQ so I'm just going to copy-and-paste my own answer from last time:

It's not as simple as that. It can be done but it's complicated.

However, Linux is free software -- there's no copy protection, no
serial numbers, no hardware fingerprinting or anything like there is
in Windows.

So you can copy an installed system from one machine to another and it
will still work.

Before you copy it, avoid installing any special device drivers for
the graphics controller.

Keep the partitioning simple and duplicate that on the other machine.
Update /etc/fstab with the new device names. Reinstall GRUB on the new
machine and that's it, you should be up and running.

No need for install DVDs or reinstallation.

But if things like "adjust fstab" and "reinstall grub" sound complex
and are not things that you know how to do or how to quickly find out,
then this is probably not a task for you, I'm afraid.
