|Did you install Windows on the new hard drive? If so, you must install your programs to that hard drive. |
You can use two hard drives or more but if they both or all have an operating system installed on them, you need to install any programs you wish to use on that hard drive.
If your intent was to simply use the drive for storage then you just need to enter the BIOS (setup) screens and change the setting for which hard drive is the first boot drive.
Then you can use the new drive for storage or you can install programs on it by using the custom installation option and changing the path (the place you want to install to).
You need to explain in more detail what you did and what you want to do.
