What does unmounting mean?
Unmounting is the present participle and gerund of unmount, meaning to remove something from the place, frame, or support in which it is fixed. The sense is especially familiar in computing, where unmounting a filesystem or removable volume tells the operating system to stop treating it as part of the mounted directory tree and, when appropriate, release the underlying device. It can also mean getting down from a horse or other mount. As an ordinary English word, unmounting is less common than dismounting in the equestrian sense and less conversational than removing or taking down. Its usefulness lies in describing the deliberate reversal of a mounting or attachment operation: equipment, storage, or a person is detached from a supporting position. In technical writing, the gerund often appears in instructions and documentation, while the present participle describes an action happening alongside another activity.

Where does unmounting come from?
Unmounting is the present participle and gerund of unmount, formed by combining the prefix un- with the base verb mount. Mount comes through Old French monter from Latin montare, ultimately from Latin mons, meaning “mountain.” The prefixed form developed in English by the early modern period, while related forms such as dismount and remount also trace back to the same Latin verbal root.
