The point is...a hard drive from one computer...cannot be expected to work as a boot/system drive in a different computer...unless it has been formatted or a user has removed the settings and drivers which were installed on the first computer.
When Windows is intalled, the settings, drivers, etc. installed...relate to that motherboard/system. Moving that drive as a system drive to a different system...will probably result in the drive/system not working properly.
If installed as an additional drive...there is no problem because it is viewed as any other secondary, non-boot drive would be viewed.
