I want to extend my Windows Drive (C Drive)  using the new Vista Extend your partition feature. But whatever I do , I dont get that option.

Here is my parition layout,



So, as you see in the above,

Dark Blue - Primary Parition (PP)
Light Bue - Extended Partition (EP)

The last three are Linux Partitions.

I have tried extending my C: after deleting one of those Linux Partitions which makes some free space in the primary parition, but still I dont get the option to extend.

Any suggestions/ideas?

Thanks
