In this example, the machine has 2 disks, 1st disk's name is sda (device name in GNU/Linux), 2nd disk's device name is sdb. We already have a Clonezilla image in sdb. //NOTE// You must first create an image and it should exist in dir /home/partimag, otherwise later the menu "recovery-iso-zip" won't be shown.
In this example, the image name is called "focal-mbr-zst-20201114":

Now we will use the image "focal-mbr-zst-20201114" to create a recovery Clonezilla live CD, which can be used to recover the sda if the system on sda crashes.
Once you have the bootable Clonezilla Live CD/DVD or USB flash drive, you can boot the machine you want to clone via Clonezilla live. Remember to use the Clonezilla live CD or USB flash drive to boot the machine. For example, if you have Clonezilla Live in USB flash drive, you have to boot it via USB device (Ex. USB-HDD or USB-ZIP). If necessary, you can set the first boot priority in the BIOS as USB-HDD or USB-ZIP so that it can boot Clonezilla Live from your USB flash drive.
Here we take CD as an example. You can either set CD as first boot priority in machine's BIOS like this:
Or by pressing a hotkey (e.g. Esc or F9) when you boot the machine, you will see the boot menu of BIOS like this:
Check your motherboard manual for more details about how to boot your machine via CD.
