Comments/Problems:

I did a pretty minimal installation with the base system but no graphical 
environmend. I used the "Guided - use entire disk and set up encrypted 
LVM" partitioning scheme. Then I chose the harddisk sdb instead of USB 
stick sda.
Installing GRUB (more precisely: configuring shim-signed:amd64) failed
with a message complaining that GRUB could not be installed on dummy 
(execution of "grub install dummy" failed).

Conclusion: I was unable to install GRUB using the Debian installer. That 
left me with a non bootable installation.

Thanks for looking into this,
Christof
