In case that there are several devices which have to be set up identically (e.g. RPis, Nucs, ...), it might be helpful to just clone memory disks, once the first one is set up completely. Clonezilla is a tool, addressing exactly this. The following describes one way of using Clonezilla which has proven itself for our purposes.
Clonezilla is an operating system and can thus be used via a bootable USB-stick. In the CPM Lab you will find a black one which contains this already. (PICTURE)
Identify names of memory disks
In this explanation, one SD-card will be cloned to another one directly. Consequently, both SD-cards have to be plugged in at the same time. Because you will need to specify which of them is the source and which the target, you need to identify them clearly. For that purpose, plug them into the computer and open Disks (Ubuntu). Their names will be the same in Linux and Clonezilla.
Note: Something like sdc is NOT the name of the device. This one changes dependent on the order in which the devices are plugged in.
Start Clonezilla at the OptiPlex 3070
To start Clonezilla you might have to change some properties in the BIOS. Plug in the USB-Stick containing Clonezilla and start the computer. You will get into the BIOS by pressing F2.
- Move to Secure Boot > Secure Boot Enable and deselect Secure Boot Enable.
- Move to General > Boot Sequence and click on Add new XY. Choose a name, select the file /EFI/boot/grubXY.cfg and confirm it. (Depending on the used Clonezilla version and the underlying BIOS the needed file and its path differ. For more information see here.) Move Clonezilla to the highest priority, apply the changes and exit. After rebooting, Clonezille should start.
