===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. How to write (burn) a disk image file to external device (except optical disc drive)==
