From here you can expand the primary partition to use the new space. You can download the GParted Live CD from HERE.

Download the GParted Live CD or whatever partition manager program you wish and mount it to the guests virtual CD and boot the guest.

Use the following command to increase the size of the drive:Ĭode: Select all Expand view Collapse view VBoxManage modifyhd -resize Įxample: I have a 10GB drive that I want to be 20GB the command would be.Ĭode: Select all Expand view Collapse view VBoxManage modifyhd -resize 20480 Note: if the path has spaces in it you will need to wrap the path in quotes.

But that wouldn't be a real problem because you made a backup of your data before trying this stuff, right?

There is a slider and a numeric control there, that you can use to adjust the VDI size.īe doubly careful before pressing the 'Apply' button, because you can only increase the VDI size, you cannot decrease it. Go to File|Virtual Media Manager, find your VDI, make sure the 'Properties' is enabled in the toolbar, select the 'Attributes' on the bottom part. Increasing the drive does not increase the primary partition so this is a two step process. Secondly when doing anything that could prove as destructive as this should you make a mistake, backup the *.vdi file before you start. First, resizing does not work if the guest has snapshots ( prior to version 4.3.*) nor will it work on Fixed drives, nor on drives which are already larger than the selected size.
