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!
