Live Installation to External Device
With a live installation of an operating system, this means that it can be run directly from an external device such as an USB flash memory drive, SD flash memory card, hard disk drive (HDD) or solid state disk drive (SSD):- bypassing the existing operating system on your computer
- without altering the configuration of the existing operating system on your computer (unless one deliberately chooses to do so in order to fix a broken system configuration)
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)
- write (burn) the disk image file (with file extension .img or .iso) to an external device
How to write (burn) a disk image file to external device
- From within GNU/Linux:
- ensure the target device is disconnected from the computer
- list all USB external devices connected to the computer, via the command-line interface:
lsblk
- connect the target device to the computer via an USB port
- IMPORTANT determine the correct device name (sdX) of the target device by invoking the lsblk command again, and comparing both outputs:
lsblk
- 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 Microsoft Windows:
- ensure an external device is connected to the computer, usually via a USB port
- use the free software Rufus (the latest version of Rufus requires Windows 8 or later; last supported version for Windows 7 is version 3.22)
How to run GNU/Linux from the external device
- ensure the external device is connected to the computer, usually via a USB port
- ensure that the B.I.O.S. is configured to follow the correct boot sequence (read Appendix 3)
- shutdown the computer and ensure that the computer is switched off
- switch on the computer
