Download the latest ISO from https://clonezilla.org/downloads.php and prepare a bootable USB key or boot pxe with Iventoy, for example

Photo 1 This is the welcome screen. It's minimalist, but that's all you need.

Photo 2 Select French at random.

Photo 3 We'll choose a French keyboard, as it will be more practical.

Photo 4 Select Latin9.

Photo 5 Start Clonezilla, of course.

Photo 6 We are going to create an image of an entire disk, so we select device-image.

Photo 7 The image will be created on a local disk, so we select local_dev.

Photo 8 Detection of available devices. We will send the image to /dev/sdd.

Photo 9 This is not the first image I have created, there is already a folder /dev/sdd1/CLONEZILLA, so I select it.

Photo 10 I like expert mode.

Photo 11 Select savedisk.

Photo 12 The machine I'm imaging is called GEONOSIS, so I chose that name + date, but you can put whatever you want.

Photo 13 Here we select the source disk, which is the system disk we are interested in.

Photo 14 I choose to use partclone.

Photo 15 Here, leave the default settings.

Photo 16 I select multicore compression because it's faster.

Photo 17 If the image storage disk is in FAT32, select 4096 to split the image into several parts; otherwise, you can set it to 0.

Photo 18 Do not verify the source disk

Photo 19 It is up to you to choose whether or not you want to verify the image once it is complete

Photo 20 It's up to you whether you want to encrypt the image.

Photo 21 It's up to you what to do when the image is finished.

Photo 22 We'll have to confirm once or twice

Photo 23 Yes, I'm sure!

Photo 24 Now you can go have a coffee or smoke a cigarette (no, it's not good for your health).

Photo 25 Once the image is complete, here is the contents of the folder.
