How do I install Debian from a live-booting-laptop

Question

Is there a way to install Debian from a running Debian with network access? Is so, can anybody point me to a tutorial?

Edit

I abandoned Windows 7 on my laptop after creating a bootable USB with Debian. I now want to install Debian. My former Windows is no longer accessible to me. Is it possible to install Debian while running Debian?

I get the install option from the USB boot, but the machine cannot find installation file on live boot USB.

I read through the U&L question What's the easiest way to decrypt a disk partition? but I might be too much of a newbie to follow the instructions.

I have cabled network access after boot.

So you're booting the Debian live USB, which fails to run the installation program because it's corrupted? Have you tried rewriting the iso? — Pheric, Jun 20 '20 at 21:53
what exactly are you asking? ... your post is somewhat confused — jsotola, Jun 21 '20 at 04:12
I succesfully boot from live USB. I can also choose install but USB cannot be read as install CD — Morten Engelsmann, Jun 21 '20 at 06:08
I am afraid I do not have the ISO on my live boot USB,. I am not sure, though. — Morten Engelsmann, Jun 21 '20 at 09:44
To do it simple, just redownload a debian install iso (using the system used to post this question) and put it again on an other USB disk — A.B, Jun 21 '20 at 12:08

Make encryption passphrase easier to type

Instead of reinstalling I opted for changing the passphrase on the encrypted volume:
