How to get to config.txt file?

Configuration

Hi,

I would like to ask for advice on how to get to the config.txt configuration file on my RPi 4B?
Some time ago, I turned off Wi-Fi in this file, and if I remember correctly, all I had to do was insert the memory card into my Win 10 laptop and get to the boot folder.
Now when I insert the card into the laptop, only a notification appears that it is necessary to format it and I am not able to access it.
I’ve read some posts on this topic here, but unfortunately it still doesn’t work for me and the methods described were very complicated for me.
In the past, it was enough to insert the card into a PC.

This is not related to home assistant.
Depending on the Os you installed, it might be very different.
Ex: with Raspberry Pi OS, you can start raspi_config from a command line.

I use Home Assistant OS 8.1
I used Home Assistant OS even earlier, when I got to the configuration file by inserting the card into the PC.

Now I have inserted a completely new memory card with HA installation into the computer and I see a separate hass-boot folder on the PC and I have access to it including the config.txt file.
So the problem was probably in my old memory cards.
