Oh well, it was lunch time and we were all hungry, thus more concentrated on food than on computing stuff. OK, then boot on the CD-ROM, start the recovery procedure. Nice, it works. Press 'Ctrl-C' to abort ... what, nothing? Oh, might be because of busybox. OK, then press 'n' ... WTF? It is now formating my partitions!!!

Yes, 'n' was to bypass fdisk but NOT mkfs. Luckily, the backup worked well (so it is validated!). Oh, bad, it was an OLD backup. Not so old, thought, so I lost only 1 or 2 hours.

Note to myself, never EVER do critical stuff before lunch. ;-)
