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.
Probably all you need to do is check to make sure things look right, and actually test it.
I can’t think of anything else that would be common that you’d want to check. If you’re running weird virtualization setups on your laptop you might have to do more. :P
