problem with the partition of drive

i do have a lenovo laptop with windows 7 in which the c: dirve has 180 gb and d: drive has 30 gb when i tried to do the partition in the disk manager there was other two drives with 200 mb and 17 gb which came by default. i shrink the volume of c: drive to 50 gb then an unallocated memory of 130 gb is created with which i am not able to create a new simple partition as there was an error saying maximum number of partitions are existing so i am not able to create a new partition and also the expand volume of d: drive was in disable mode please help me to solve the problem.

The error is that you have already created 4 primary partitions which is the maximum limit of the hard disk . You cannot create more of them directly .You must have created partitions making them logical one.
>Now as you said , you have 2 other drives with 200mb and 17gb space.
>I recommend you to delete one of them (preferably 200mb one).
>Then you will have 3 primary partitions and some 130+ gb of unallocated space.
>Right click that space and make it a new partitions and format it to NTFS :). Enjoy !

You can try Partition magic or Free partitioner to partition your drive. Just delete one of your primary partitions after taking backup and reformat it to logical drive.

Be careful! That 200 MB partition is likely the windows boot partition and the 17 gb the Recovery partition. Check in lenovo forums before deleting anything.
