Can someone help? I am in computer management in Windows 7 and would like to somehow use "unallocated space" of 40gb to further expand and extend my Windows 7 partition of 325gb, but the option is grayed out. I can shrink the Windows 7 Partition, but can't seem to extend it. In the diagram, this is the order of my partitions: 325gb (Windows 7, NTFS & Primary Partition), 89.13gb (Ubuntu (Linux) 10.04 & primary partition), 3.82gb free space, 39.75gb unallocated space, and 7.79gb for a recovery/respawn (oem) partition (primary partition). Anyone know if its the order of my partitions thats the problem and thats why i can't seem to extend the partition? Any help would be appreciated. Thanks

If you would like to extend a drive, the unallocated space must be next to the drive. That should be the problem. You may be not able to extend the C drive because no unallocated space is next to it. Arthur Xie - MSFT

so how do i move the unallocated space next to the C:/?

It is impossible. If you remove the drive D, you may be able to extend the C drive with the unallocated space from the removed D drive. Arthur Xie - MSFT

Hi, Although Arthur Xie explained the reason why the Extend Volume option is greyed out, I disagree with the Answer. In fact, we can move unallocated space with some third-party software without removing other partitions. http://www.partition-magic-windows7.com/res/extend-system-boot-partition-windows-7.html
