Thank you very much for your concern brother,
I have reinstall win 7 Home Premium through PC restore.
I have got the problem in creating new Volume.
Before PC restore process I have already made 142 GB as "Free Space" and 146 GB in C:/ Drive of 320GB SATA HD.
Now the OS is in 146 GB partition.I made a shrink, to have 80 GB in C:/ Drive .
As a result an unallocated partition 66GB is formed between Drive(C) and Free space.
I tried to create a new simple volume out of 66GB, but after clicking Finish button at the end it shows
"You cannot create a new volume in this unallocated space because the disk already contains the maximum number of partitions".
After this surprisingly I have created two Logical partitions(50 GB & 52 GB) from the Free space leaving 40 GB.
Please help me how to create a primary partition out of unallocated 66.42 GB partition.
My disk Management show (as in order)
My system details
ell studio 1555,windows 7 Home Premium 64 bit,core 2 duo T6600,320 GB SATA HD,3GB RAM.
