no partitions seen in installer dialog, gparted shows partitions correctly

[Removed by request]

This is a HP Elitebook 2760p. With gparted, I've removed one of the 4 (annoying) primary partitions, added one extended with some logical drives. Unfortunately, Installer does not show the partitions, there is a plain /dev/sda entry only. What's the matter?

Hello, I did some further research and recognized this as an ancient issue. Partman fails under certain conditions - for example unordered partition numbers. Thus, I've removed the extended partition with it's logical drives and recreated the partitions with installer / partman instead of using gparted. Before, I've created the last logical drive first, this time the logical drives were created starting at the beginning of the extended partition.
