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.
That worked really well! I got a 50gb partition with about 30gb free space into a 10gb zipped image. Is there any way to show progress during the operation like with dd's status=progress?
I often use pv instead of cat for this. And there's some 'hack' where some tool looks at some kernel feature to guess progress of cp & co. But i forgot it's name.
