Hello,

After a lot of code-chasing it appears the problem is that
grub-installer script fails to set its $bootdev variable:

grub-installer: info: Installing grub on ''

(note the empty quotes)

The target system has two 'disks'. The first has Microsoft Windows Vista
with 2 NTFS partitions using msdos label/MBR. The second is empty and intended
for the Debian OS and boot-loader.

The system boots in BIOS/Legacy/CSM mode.

I suspect this is yet another avatar of bug #1035096, for which Isubmitted a patch, see<https://salsa.debian.org/installer-team/grub-installer/-/merge_requests/17>.
