How to Install to HDD from LIVE USB Flash Drive?

[Larry Dighera <LDighera@att.net>]

I just burned Debian-live-testing-amd64-lxde.iso
https://cdimage.debian.org/mirror/cdimage/weekly-live-builds/amd64/iso-hybrid/debian-live-testing-amd64-lxde.iso
from
https://cdimage.debian.org/mirror/cdimage/weekly-live-builds/amd64/iso-hybrid/
to a 16GB SD card, and was hoping to be able to install it on a partition on
the m.2 SSD next to dual-boot Win10. 

I read on one of the Debian.com pages
https://www.debian.org/CD/live/index.en.html , that there's supposed to be a
"launcher on the desktop that can be used to install while running the live
image." Unfortunately, I didn't find one.

I Googled, but was unable to find any information on how to install from the
live system.

Is anyone able to offer a pointer to the method of installing to HDD from
the live USB image?
