1. The machine pre-installed vista basic (which I can not be determined, because my N80 preloaded with VISTA, the insurance point, this article also listed on the inside) 
2. SLIC2.1 refresh with the BIOS, a specific model and version of the corresponding Web site you can find bios.net.cn. 
3. Modify the machine readable Part Number (ie BT tool), method: 
First, download the tools BT, such as stored in the D drive into DOS, type 
bt spaces / w space 27 space 47 (Note that the center has a space) 
The code is as follows: 41 is the Home Basic version of 43 is the Home Premium 45 is a commercial version of 47 is the flagship edition 
When prompted return = 0 says that the success of changes 
4. Into the Recovery Disk can be resumed at the corresponding version of the win7
