I have some space left (70 GB) in the end of my drive where I would like to installe Lubuntu. However I can not get gparted to create more partitions. I get an undefined error.
My partitiontable is as follows:

sda1-8 are my 4.1 partitions
sda9 is root on Ubuntu
sda10 is a linux swap
sda11 is Ubuntu home
sda12 is Debian root
sda13 is Debain home (mounted in Ubuntu)
sda14 is OpenSuse root
sda15 is OpenSuse home
sda16 is a NTFS partitions for exchanging data
I have a feeling that I need to create some kind of an extended partition or something but I am not sure and CFE is not your standard kind of BIOS
