On your two computers, does it say anywhere on it the windows serial key? Its usually posted somewhere on the computer for pre-builts with installed OS. If you have that key, then you can use the same windows 7 disc for every re-install. All you need to do is enter the corresponding serial key that goes with the computer.
in other words:
So you have "laptop A". If you can find the windows serial key posted somewhere on that laptop (sticker somewhere on the computer itself most likely) then we will call that "Serial A"
Now, you also have "laptop B". Find the serial key on that as well, we will call that "serial B"
Now you buy Newegg.com - Microsoft Windows 7 Home Premium 64-bit 1-Pack for System Builders - Operating Systems
giving you "serial C" to install on "desktop C"
Now you want to reformat "laptop A". Insert the disc that you bought, and during the installation, use "Serial A" key. This Will work.
