Copy system files and create a second system

[fouRmi <sunrui82@xxxxxxxxx>]

Hi all

I am a student in China. I am doing some experiment on system backup
things. And i met some problems that confused me. I copy files, most
of the files in system root directory, to another partition of the
disk to make a second OS. The current situation i am in is that I can
boot up the computer with some low level of UI abnormals, which can be
acceptable. But when i hide the former system partition from DPT(Disk
Partition Table), the second OS cannot boot up. It handed up when
loading personal statistics. But i copy the documents and settings
too. And it seems that the OS is still loading the files from C:\.
What can i do? can i make the second OS independent absolutely?

Wish to talk about this with you. Thanks.
