====How to Flash (Write) a Computer Operating System (O.S.) to an Internal Data Storage Device such as H.D.D. or S.S.D.====
- **Verify sufficient free space available** on the target partition of the internal storage device, using the command-line interface: %%df -h%%
- **Flash the O.S. to an external storage device (E.S.D.)**
~~-LiveUSB
~-**Power-off the target computer**
~-**Keep the E.S.D. connected** to the U.S.B. port
- **Power-on the target computer and set BootSequence**
~~-If the computer does not boot/start from the E.S.D. it will be necessary to either access a boot menu, or the U.E.F.I/B.I.O.S. firmware settings, so that the computer is instructed to boot/start from the E.S.D. (and not any internal storage device)
~~-Re-starting will be necessary in conjunction with using the correct key(s).
- **Configure the keyboard, locale & timezone settings** {one is offered to do this either during start-up or immediately after}
- **Prepare the internal storage device** (OPTIONAL)

~~-After any modifications re-start the computer __without saving__ any changes and with the E.S.D. connected
- **Install to internal storage device** (H.D.D. or S.S.D.)
~~-//[[https://murga-linux.com/puppy/viewtopic.php?t=29653 Menu > System > Puppy Universal Installer]]//
- **Power-off completely** the computer
~-**Remove/Disconnect the E.S.D.** from the U.S.B. port
~-**Power-on** the computer
