How to create a copy of one partition on another?

Question

Hard disks

I have Ubuntu on one of the hard drive partitions. Now I bought a 512 SSD - of which 256 allocated a partition for programs in Windows on NTFS, and left 256 for Ubuntu transfer.
Only now I can't figure out how I can copy Ubuntu from a hard disk partition to an SSD partition without affecting the other SSD partition. Because Acronis can now clone a hard drive to an SSD, but this will kill all partitions on the SSD.
How to transfer Ubuntu to SSD without loss?

Answer 1

confusing partitions on the device (ssd or hdd) with the device itself. you can copy from place to place and both.
no need to clone the whole hard drive to ssd. copy only the necessary partition with ubuntu.
then restore the boot record is rude (articles in tyrnet million) and everything is ok.

Answer 2

clonezilla is
a great set of linux utilities plus an optional boot disk, solves a bunch of cloning and backup problems

Answer 3

dd utility.
Just carefully find out where is which section and what is its name. For example using gdisk.
Here is an example how to clone:
