It happened like this: I had only Ubuntu in my system and wanted to try OpenSuse as well. When the Suse installation started, it gave me 3 options -
1 - User entire hard disk
2 - LVM
3 - Manual Partition

I selected the LVM, where it partitioned the system as you see in the Gparted. If you see the attachment in first thread, OpenSuse has took only 20 odd GB isnt it?

Please let me know whether I need to have a complete installation again or is there a way out.
