[SOLVED] GParted - Extended Partition option greyed out

view story

http://crunchbanglinux.org – I have 50GB of unallocated space that I want to use on my hard drive. I want to turn it into an extended partition so that I can have two logicals contained within it (probably one 10GB and the other 40GB) but when I go to GParted and right click on the space and select "new" the Extended partition option is greyed out and I can not make anything but a primary partition. Is there another way to do this because I feel as though it should be a pretty simple task...open space, turn it into extended space... (HowTos)
