Usage
- To clone a hard disk partition from a dual-boot system
Requirements
-
A USB flash drive
It will be used to boot Clonezilla.
-
A hard disk drive
It will be used to store the copy of the partition.
Warning
Make sure the total space of this hard disk drive is larger than the size of the partition you want to copy.
For example, if you want to copy a 512GB partition with 100GB used space, the hard disk drive should have at least 512GB space. If the hard disk drive has only 256GB space, although it is enough to store the used space, the copy process will still fail.
Steps
Prepare the Disks
-
Download the Clonezilla iso file from the official website.
-
Burn the iso file to the USB flash drive using Rufus or Raspberry imager.
-
Divide the hard disk drive into two partitions using GParted or Gnome-disk-utility.
The bigger partition will be used to store the copy of the target partition.
The smaller partition (0.5-1GB is enough) will be used to store the copy of EFI system.

Notes
Info
There might be an another way to copy the both EFI system and Ubuntu at the same time (choose device-image instead of device-device work directly). However, I have failed serval times, I will update this note if I find a way to do it.
