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 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)

From within GNU/Linux (select one of the following)

MX Live USB Maker AppImage

SystemRescue USB Writer

USBImager

EasyDD

dd command

ensure the target device is disconnected, or remove all removable USB devices, from the computer

next, list all known disk devices connected to the computer, via the command-line interface:
```
lsblk -al
```

next, connect the target device to the computer via an USB port

next, determine the correct device name (sdX) of the target device by invoking the lsblk command again, and comparing both outputs:
```
lsblk -al
```

then, write (burn) the disk image file (with file extension .img or .iso) to external device, via the command-line interface

WARNING the dd command will overwrite all existing data on the target device X, where X represents the device letter for your target device - USE ENTIRELY AT YOUR OWN RISK:
```
time sudo dd bs=4M conv=notrunc,fdatasync oflag=direct status=progress if=<DISK IMAGE FILE> of=/dev/sdX
```

From within Android:

ensure an external device is connected to the smartphone/tablet, via the USB port

then, use the following free software program:

EtchDroid

From within Microsoft Windows:

ensure an external device is connected to the computer, usually via a USB port

then, use either one of the following free software programs:

Rufus (the latest version of Rufus requires Windows 8 or later; last supported version for Windows 7 is version 3.22)

Fedora Media Writer

USBImager (User's Manual)

2b. How to write (burn) a disk image file to external device (optical disc drive only)

go to LiveDVD

3. How to run GNU/Linux from the external device

ensure the external device is connected to the computer, usually via a USB port

next, ensure that the U.E.F.I./B.I.O.S. firmware (low-level software that starts just prior to the operating system doing so) settings is configured to follow the desired boot sequence (read Appendix 3)

next, ensure that the computer is put in a power-off state

next, power-on the computer
