- name the clone "oUextended" (or wathever you want)
- on host under a shell : go under oUextended directory and use this command to extend for example to 25GB the hard drive :
c:\Users\myuser\VirtualBox VMs\UBUNTU_EXTENDED_25G>"c:\Program Files\Oracle\Virtual Box\VBoxManage.exe" modifyhd UBUNTU_EXTENDED_25G.vdi --resize 25625
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
- on virtualbox : oUextended/configuration you should show the hard drive size : 25G (==25625MB)
