  • Hi there,

    If you want to extend volume, you should make sure there is no partition between the original partition and free space (PS: it will not work if the free space is in "Extended partition"). Attached a simple screenshot in my test machine:

    If you have dual-boot Windows XP and Windows 7, I suggest you create new partition with left free space and mount this partition as a folder to XP (or Windows 7 ) partition which is quite easy.

    What do you think about it?

    The OP is right on this one, and the replies are not accurate. I too have Win 7 installed on C: and on its own during setup is used only 100gb of my 1tb drive. So I have 900gb unallocated.

    Win 7 will not allow C: to be extended to use the unallocated space. The option is grayed out.

  • It is may be a little bit better and reliable solution if you have an additional hard drive:

    1. Move all data from the logical that you want to use as a donor.

    2. Delete the volume

    3. Extend your acceptor volume

    4. Move back your backed up data from your extra storage

  • There is so much misleading and incorrect information in this thread.  You certainly can extend a boot volume in NT 6.1 (Win7/Server 2008 R2), as long as you first convert the volume to a dynamic disk.  You do this by right-clicking the Disk (not the volume) in Disk Management and clicking "Convert to Dynamic Disk", or by running the required commands using diskpart.
