I tried to reinstall: This time I said guided partitioning the whole disk but it only creates a 1M partiion for biosgrub and a big one (3TB) for everything else (+ swap).

That is how it works for me when I boot the installer usb in legacy bios mode regardless whether EFI is enabled in the bios.

I just now inserted a Debian 12 installer usb and rebooted, making sure to catch the bios boot device selection screen. It presented me with 9 boot options:

# 6 was "General UDisk 5.00"

# 9 was "UEFI: General UDisk 5.00"

My other 7 boot options are irrelevant to this.

If I boot the 6th option and install Debian it will install like you described above. If I boot the 9th option and install Debian it will create, among others, an efi partition mounted at /boot/efi that will not be empty.

If I did not have EFI enabled in the bios then my boot device #9 would be missing from the above list.
