I'm trying to resize XP partition, the procedure suppose to be simple: VBoxManage modifyhd /full/path/to/hd.vdi --resize new_size
so, I run: VBoxManage modifyhd /home/joseph/VirtualBox\ VMs/xp-clinic/xp-clinic.vdi --resize 15000 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% The original size was 10G and still is. -- Joseph
