To make the long story - short, it works!
There are a few things which are not set/clear and I would like to clear
out, like for example:
1. Why the installation offered me lilo, not grub? I guess when I switch
to grub, I would still have the same problems as before..
2. Why the drive letter assignment changed before and after the
reboot(comparing the partition table list and the fdisk log)
3. What do the entries from fdisk -l like "Disk /dev/md1 doesn't contain
a valid partition table" mean?
4. What are devices /dev/md-0 and /dev/md-1?
All of those I'll try to solve. For details see below.
Thanks again,
Ivan

Log of the installation (only the relevant entries):
01. I downloaded the image from the address you point me to:
http://ftp.nl.debian.org/debian/dists/etch/main/installer-amd64/current/images/netboot/mini.iso
03. Booted from it.
04. Hit enter in the boot screen.

24. Partition disks - Finish partitioning and write changes to disk
25. Partition disks - Write the changes to disks? - Yes
31. Software selection - "Standard system" & "Desktop System"
33. Install the LILO boot loader on a hard disk - Other choice (the
default is /dev/md1) <<< why LILO?!
34. Install the LILO boot loader on a hard disk - /dev/md0
35. Reboot - working!!!
