resize clone vdi image using Virtual box

Resize An Existing .vdi Virtualbox Image

Start off by creating a fresh new drive of the size you're after using the VirtualBox user interface. Then, locate both the your old, smaller HD and the new, larger one and run the following command:

VBoxManage clonehd --existing oldhd.vdi newhd.vdi

After some progress indicators ahve come and gone your HD should have been cloned to the larger one. You now need to use some software to expand your drive partition into the new space. Vista and W7 have this feature built in to Disk Management, or you could use something like GParted. I have never had luck with the integrated windows disk management tools, so I opted to use a free product called EASEUS PARTITION MASTER – home edition:

resizer_tool

This tool was easy to install directly into the new vdi image.  Walked through the wizard after clicking on "Resize" – it rebooted itself and resized the partition without a fuss.
