Well one of those partitions is 100MB not 100GB :) I guess that makes the equation correct. PC consists of a Intel DG43GT main board, more tech information is available at <a href="http://www.intel.com/cd/products/services/emea/eng/motherboards/desktop/DG43GT/overview/424010.htm">http://www.intel.com/cd/products/services/emea/eng/motherboards/desktop/DG43GT/overview/424010.htm</a> No HW RAID. I'll boot it from a live cd and check what you have suggested. Thanks a lot for the reply.

What kind of storage controller? Hardware RAID? The problem is Kubuntu either has no driver at all for your storage controller, or the driver does not have support for that particular chipset. One way you could find out would be to boot the live cd, open a terminal, and use lspci to see if the controller even shows up as a PCI device. <div class="im"> > Already posted this to Kubuntu mailing list, and I guess there is no much > difference in this area. </div>No, functionally there is not. This problem has nothing to do with KDE based Ubuntu vs GNOME based Ubuntu... it's a storage controller issue. I have a feeling your PC is super new, or it's one of those fancy "Made For Windows 7" PCs that has odd hardware. My students have had problems in the past with certain brands of PC and Laptop that are "Made for Windows $VERSION".
