You pic looks odd! As per the color legend, it has 5 primary partitions+1 extended partition! All I know is we can make only 4 primary or 3 primary+1 extended partitions.
Is 2.93GB your swap and 40.69GB is your Ubuntu root partition? Is the partitioner able to delete it? I would suggest delete 2.93GB and 40.69GB partitions, extend your extended partition to fill the free space after deletion. Then try making partitions for linux. That way your current D drive will be sda5, other linux partitions would start from sda6 onwards.
If Mandriva partitioner is not able to edit try gparted/parted magic live cds.
Please wait for reply by other seniors. I'm equally confused.
