How to expand a WinXP virtual disk in Virtual Box

(Thanx to user "gushy" in this thread) do the following:
  • Create a new disk using Virtual Disk Manager (in VirtualBox goto File -> Virtual Disk Manager)
  • download System Rescue CD
  • set your current VM to have the new disk image as it's second hard disk and the System Rescue CD iso file as it's CD
  • boot the vm from the CD
  • at the command prompt type startx
  • when X Windows starts, type gparted in the terminal that is open on screen
  • in gparted select the windows partition and choose copy
  • select the second hard disk
  • right click on the representation of the disk and click paste
  • gparted will prompt you for the size of the disk, drag the slider to the max size
  • click apply
  • wait .......
  • when it's done right click on the disk and choose Manage Flags, and select Boot
  • exit gparted and power off the VM
  • change the VM settings to only have one disk (the new bigger disk) and deselect the iso as the CD.
  • boot the VM into your windows install on it's new bigger disk!
