I have windows 7 ultimate installed on my dell Inspiron N5010 machine.I had a preinstalled windows 7 home basic.

I have currently 4 partitions:

OEM
Recovery
1 Primary partition with aorund 250 GB
1 extended partition with 2 logical drives.

Whats My Problem??

Out of the free 225 GB , the maximum available shrinked space available is 128 gb (thats is understable ,due to unmovable files ~hibernation files etc).I shrinked it to maximum capacity to create a new unallocated space of 128 gb.But when I tried to create a simple volume, it gave me an error~You cannot create a new volume in this unallocated partition beacause the disk has already maximum number of partitions.

I guess,out of the permissible 4 partitions in disk management without using any 3rd party software,I have used it all.And when I tried to create a new simple volume, it is creating another partition.

Real Problem:
How to create a logical drive from primary partition??

PS:I tried PM, but it gave me a launch error.
