I know about Clonezilla and copy pasting partitions with gparted, but can I just use dd to copy a partition with batocera to a USB stick and will it then boot from the stick? Do I have to set the boot flag or take any other steps?
Thank you for any tips.
There are different schemes that different distros use. Some user partition id, some use fire system id, and some use device serial number and partition index.
