Both trixie and its installer (d-i) are evolving and may not give you useful results. I suggest you use the current Stable, Debian 12.8, bookworm. > Expert mode installation During installation Debian does NOT see my > disk at all (pendrive with Debian Trixie is visible only) Interesting.

Make sure it is set for UEFI booting. Secure boot should probably be off, but you should be able to turn it back on when you are done. > > Second try: > Secure Boot set to OFF. > Nothing changed during Trixie installation, so no device to install > on. > > Third try: > Boot in Legacy Mode (so Secure Boot is OFF). > Debian Trixie can see my laptop disk properly, so installation is > successful, but... > It cannot see my Windows 11 installation when trying to > install/configure/prepare GRUB. > At this step I decided to NOT install GRUB on my main disk to NOT > loose access to my Windows 11 system. > (but Trixie says that it's possible to restore access by manual > configuration of GRUB later on - I'm not sure...) > > Main goal: > To have both current Windows 11 and new Debian Trixie available in > GRUB and properly bootable.
