I have this 40 GB volume (partition) that I would like to extend to 80 GB. I have already shrinken (downsized) the system partition in order to create some unallocated space before the partition that I want to make bigger.


The problem is when I right click on the 40 GB partition I can't select the "Extend volume" option. Why not? You can see by the screenshot above that the space before my partition is "RAW". That's because I formatted selecting any file system. But it was black before, indicating "unallocated" space, and I still couldn't extend my partition to include this space.

Let me guess... I have to have the unallocated space AFTER the partition I want to enlarge? I would like to try that of course, but there seems to be no option to move any partition or "volume" anywhere, not to a different disk nor left or right within a given space on the same partition. So how do you do it then?...


In the screenshot above you can see how it looks like with unallocated space before my partition. I obviously can't just remove my RECOVERY partition that sits right after my partition. I won't be able to restore the computer ever again. So that's not an option.

  • You tried a third party tool? – Re Captcha Feb 25 '14 at 10:05
  • I'm not really supposed to install any applications on this computer. It's my work computer. So I would rather use built-in Windows tools if at all possible. – Samir Feb 25 '14 at 10:06

    So either that or prep a Gparted disc then?... – Samir Feb 25 '14 at 10:15

    Yes, I do have a DVD reader in this computer. I find that Linux live systems on USB are just troublesome. And yes, that's why I use Acronis Disk Director on my private computers. But this is Windows 8? Come on? Surely, M$ must have improved essential tools like the disk manager (diskmgmt.msc)?... I know it looks old but they could have enhanced it under the bonnet. – Samir Feb 25 '14 at 10:23

    Are there morons working at Microsoft or what?... Sorry, but I can't help it, I just don't get them at all... This is the latest version of Windows 8 on this computer but I have the same problem partitioning disks as I did several years before with previous Windows versions. Disk partitioning is kind of an essential function of any OS, it's not like I'm asking to much here... whatever... I'll try to get Gparted Live working today. – Samir Feb 26 '14 at 11:53

The way that Windows does it's partitioning, you can only extend volumes forward, because the RAW space is technically behind the volume, it can not expand out backwards. You would need to use some 3rd party tool, or expand the C:\ to take up the space allocated to it. It's just the way Windows operates. Booting from an external media, such as USB or CD/DVD will allow you to modify the HDD partitions and write the changes that you want to use.

I was not able to use any tool to simply extend my C: partition as I had two recovery partitions in between my unused space and my C:. I had to first move the two partitions that were in between my C: and unused space to the right-most edge of the unused partitions and then I was able to extend my C:. I used the free version of EASEUS Partition Manager (http://www.partition-tool.com)

  • So what tool did you use then? I don't think you can "move" partitions with Disk Management, and that's the PITA. – Samir Dec 23 '14 at 8:36
