how to extend a disk partition in vmware virtualserver

Hi all,

i have enough space in datastore. so i shutdown my windows 2008 server and expanded the disk.

but how can i extend a partition now from disk management. the option is greyed out.

there is around 150GB unallocated space showing but when  i right click the partition to extend  a volume is not available.

i want to expand two partitions one is E and other F . there are other partitions also like G and H.

how can i do that.

Regards,
