Help with initial installation needed

What is the problem?

I am trying to install a fresh copy of octoprint over an existing installation (which is working) before donating the printer & octoprint to the local library. The raspberry pi installer requests the storage to write to, but the raspberry pi 3 doesn't show up in the list of available drives. I don't want to write to the internal drives in the computer - what do I do? I need to get past this to continue the installation. The installer version is Octopi_imager_2.0.0.

What did you already try to solve it?

Have you tried running in safe mode?

No

Did running in safe mode solve the problem?

No

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

The Raspberry Pi OS is (usually) booted from a microSD card. To install a fresh version of the OS requires flashing the new version onto a new microSD card (or removing the existing card from the RPi and writing over it).

The most common way to flash a new image is with an USB to microSD adapter. You can plug this into the system that the imager is running on. You can obtain one of these adapters from Amazon, search for "usb sd card adapter".

For detailed instructions, see https://www.raspberrypi.com/documentation/computers/getting-started.html.

If you have a USB flash drive, it is possible to copy the OS to it and boot an RPi 3+ from it. See https://www.instructables.com/Booting-a-Raspberry-Pi-From-USB-No-SD-Card-Needed/.

I strongly recommend obtaining the USB adapter.
