  • 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 volume extension is meant for RAID arrays etc. Not the boot volume.

    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.

  • The only way to get all the space in use, is to install it and use the full disk at that time. You cannot extend the boot volume.

  • Use a good Windows 7-specifc partitioning tool (that's also free), like EaseUS Partition Master Home Edition.

    I just used it to grow the size of the C volume on a new Windows 7 Home Premium 64-bit laptop after deleting two other volumes and ending up with both 'Unallocated' space to the left and 'Free' space to the right, which I could not extend into with the Windows Disk Management.

    1. Download and fire up EaseUS Partition Master.
    2. Click the Resize/Move button.
    3. Extend the C: partition size into either one of or both the left-side and right-side disk space, hit OK.
    4. Go to exit the program and you'll be prompted to run the unsaved changes and reboot.

    While rebooting you'll see an EaseUS boot screen with a partition resizing progress indicator for a couple of minutes, then Windows will load normally.

    Really simple.

  • 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.
