I am trying to copy a partition and make the copy bootable (the original is bootable). Step 6 of MovingLinuxPartition refers to something called [instance]. What is that?
Given that one of the consequences of guessing what this means incorrectly is that my computer will become entirely unbootable, I am reluctant to just go blindly guessing.
The "disks" application is actually gnome-disks. Is there a CLI equivalent for if you are working on a server?
