If I have a laptop which is running Vista Home and has installed applications.
I do not want to format this drive at this time.
If I install a new blank drive and install windows 7 and applications on it.
and want to retune to my Vista drive, can I just plug it back in or will the Windows 7
drive maked internal changes to the laptop..... if so what changes and what do I need to do
to make the Vista drive work again?
