From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Can I just use dd to clone my laptop to a bootable USB stick? (suppo.fi)

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.

huh?

Isn't it the other way around?

I once cloned an nvme with dd and had to physically remove one of the two, because they had the same id and the bios couldn't differentiate between them and would randomly boot into either the first or the second one, inconsistently.

And removing either one would boot into an identical system with everything mounted and working. Which caused some confusion until I realized that the id was copied over.

So unless you didn't use the id in fstab, you should be fine. Sure the device path may differ, but that can happen anyway to usually devices should be referenced by id.

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.
