This kind of copying an entire OS is inelegant, clumsy and may lead to instability.
In my opinion, it should never be done except by peeps that don't know better.

It is so much simpler to image the drive and store the image on a separate drive/partition or on a bunch of CDs and then restore.
Even in copying ME/XP, you gotta be careful to first delete the page/swap file because if you don't it will never complete the copying operation.
But, Creature, you have all disks so don't try and copy the OS like this.
