I'm going to be buying a 1TB Hard Drive from Scan to install Windows 7 on and use as a primary drive, retiring my current primary into a downloads/storage drive. However, I want to preserve all the data currently stored on my CURRENT primary drive (the one which will become a storage drive). The problem I'm having is understanding this- if I install W7 onto my new drive, will the secondary drive get wiped? After I've installed W7 on the new drive I want to move my files such as music, pictures, etc. over to my new drive from the old one, and then format the old. What will happen to my boot manager in this process? How do I REMOVE W7 from a drive, instead of just formatting it? (I had a problem with formatting a Linux drive messing up some GRUB manager in the past- I don't know if Windows would have similar problems?) Sorry if my post is poorly worded- I'm not entirely sure of a better way to put my problem unfortunately. Thanks, MrBobandy.
