Not quite, I mean, I am typing the characters of the encrypted partitions password and the sytem spontaneously goes on booting and asks of the next partition password.

This is a longer story. Let me short explain. I installed kali-linux on a second drive. During this installation, the kali installer overwrote grub with its version. As I could not restore grub again, I decided to install debian on the first hard drive again. So I installed new, with the same partition structure as before - same size, same construct (/ and /boot unencrypted and /home, /usr and /var encrypted).
The installation was unencrypted. When the system was up and running fine, I backuped all data from /home, /usr and /var to another computer via rsync. After this I encrypted /home, /user and /var, made ext4 filesystem as before and rsynced the data back.
Finally I edited /etc/crypttab and /etc/fstab with the new UUID's, checked the mountpoints and did not forget to create a new initrd with added modules aes, dm-crypt, dm-mo and sha256.
I have two more computers running exatly with the same construct. Both debian/testing and both show no errors.

IMO there are only crypttab and fstab as editable files involved or did I forget one?
Thanks for the help, I really appreciate this!!! > Cheers, > David.
