Live Installation to External Device
With a live installation of an operating system, 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, internal operating system on ones computer
- without altering the configuration of the existing, internal operating system on ones computer (unless one deliberately chooses to do so in order to fix a broken system configuration)
1. How to create a live installation to external device
- acquire the disk image file (with file extension .img, .iso or .zip) of the desired operating system, such as a recent Puppy Linux release (read Appendix 2)
- write the disk image file (with file extension .img, .iso or .zip) to an external device
2. 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, .iso or .zip) 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 either one of the following free software:
- Rufus (advanced) (the latest version of Rufus requires Windows 8 or later; last supported version for Windows 7 is version 3.22)
- USBImager (simple)
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) is configured to follow the desired boot sequence (read Appendix 3)
- next, ensure that the computer is in a power-off state
- power-on the computer
