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.
Its not necessary better as tar by itself doesn’t have compression. You need gzip, bzip2 or something else. On modern systems with gnu tar can handle tar with compression.
If your still curious I would look up how to use it.
