[PROBLEM] SSD Media / System Partition Issues

[Nutul]

I followed your sage instructions using Rpi Imager and referred to your comprehensive thread

As many have said, things do work if the necessary initial steps are followed.

1. start Pi Imager
2. select the image to flash
3. click on the cog-wheel
4. now specify a username + password, a wi-fi access-point + password, and enable ssh
5. confirm the configuration and flash the image.

There's nothing more to it, no additional guides (the guide of @TheOldPresbyope is valid and useful only if for some reason you cannot use the Pi Imager, which as I understand, is not your case any more). It really takes a few seconds to configure everything. Give it another try, following my easy steps above.
