===Live Installation to External Device=== With a **live installation** of an operating system, it can be run directly from an external device: ~-//bypassing// the existing, internal operating system on one's computer ~-//without// altering the configuration of the existing, internal operating system on one's computer (//unless// one deliberately chooses to do so in order to fix a broken system configuration) With a **live installation** of an operating system, it can be run directly from an external device such as: ~-SD flash memory card ~-USB flash memory drive ~-solid-state drive (SSD) ~-hard disk drive (HDD) ~-optical disc drive (see [[LiveDVD]]) ==1. How to create a live installation to external device== - acquire the disk image file (with file extension //.img// or //.iso//) of the desired operating system, such as a recent Puppy Linux release (read [[https://wikka.puppylinux.com/LiveDVD Appendix 2]]) - then, write the disk image file (with file extension //.img// or //.iso//) to an external device ==2a.
