windows - Creating partitions for multiple operating systems

I changed my old 120GB harddrive to a new 320GB harddrive. I am using multiple booting, I have two OS: Windows 7 and Ubuntu. My laptop's partitioning table:

1. System reserved, 100MB (Windows 7), NTFS, Primary


2. Windows 7 itself, 93,15GB, NTFS, Primary


3. Logical, ext4:
   
   
   
   
   
   • SWAP, 2GB
   
   
   • Ubuntu itself, 16,63GB
   
   


4. Unallocated 186,30GB

I want to resize both OS partitions so that both partitions would have ~150GB size.

Is it possible? I have tried Gparted and EASEUS Partition Master, but couldn't succeed.
