Reboot and select proper boot device

I've installed debian 12 on my new ssd.
It worked properly until today, when i turned on my laptop and i got this error on black screen "Reboot and select proper boot device".

Now:
1. I've replaced my ssd with my old hdd with deb11.
2. I've connected my new ssd(with deb12 on it) to the laptop with a USB3>SATA Cable.

I suppose is a grub error. Am i right?
What can i do to solve the problem and put my ssd back into the laptop?
