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.
Small USB flash drives are still available, you just won’t find them in the local stores. There are expensive, industrial grade drives from places like digikey and dirt cheap, no name drives from Chinese sellers where they will print your logo on them for free if you buy a hundred of them.
