using the install data in the hidden partition to create a virtual machine

[Bill Stanley]

I dual boot on a Dell machine which originally had Windows installed.  I now am 
running Unbuntu but still have the original Win XP partition.  The machine I 
have is rather old but with upgrades is still running well.  This gets to my 
question.

I want to run a VBox machine with the original Win-XP OS.  I never received any 
Win-XP installation disks but I know that Dell puts OS install data in a small 
hidden partition.  I can see that partition with Unbuntu Linux so I know it is 
there.  Also, Windows activation is not going to be a problem because this was a 
Win-XP version before M$ had their crazy activation scheme.  The fact that this 
will be a rather old OS is not an issue because I am going to use it for legacy 
stuff.  Is there any way to use this for making a virtual machine?  If it can be 
used, how do I do it?
