I accidentally clicked "Cancel" in the Raspberry Pi setup tool that runs on the first boot. How do I get it back? If I can't, which settings do I have to change to make the Raspberry Pi run as it is all setup? (ex. fix display not filling monitor)
As I understand it, the tool you accidentally cancelled is known as
piwiz.desktop (also known as the "First-run Wizard"), and it is located here:
You might first want to check to see if it's still there, and re-start it if you can.
Another alternative is to re-flash your SD card using
rpi-imager. Follow these instructions, use the "Advanced Options", and select the "Skip first-run wizard" option. That should give you a system that boots as you want - without using the
You will of course need another operational RPi system to install and run
rpi-imager. If you don't have one, and my first suggestion wasn't available (can't restart
piwiz.desktop), you may need to start over with a freshly-flashed SD card using the tool you used to flash your card the first time.
Hope that's clear; I've only just learned of this craziness.
