Windows 7 - upgrade vs. full version

I want to buy Windows 7, what is the difference betwen upgrade and full?

Is the "upgrade" mean that I must have some other Windows install already?

Example:
Windows 7 Home Premium Upgrade
Windows 7 Home Premium

Currently, I have Linux installed on my machine, can I buy Windows 7 Home Premium Upgrade and installed and use it?

In order to install the upgrade version of Windows 7, you must have a qualifying Windows operating system installed and activated.  You cannot install an upgrade version of Windows 7 on a blank hard drive.  The installation procedure does not ask you to insert a Windows disc in the drive for verification, the actual qualifying operating system must be installed.

    If you do not have a qualifying Windows operating system installed with a genuine license activated, then you cannot use the upgrade version of Windows 7 - you would need a "full version" Windows 7 license.

    In summary:

       1. A qualifying Windows operating system must be installed.
       2. The qualifying Windows operating system must have a genuine license (product key) and it must be activated.
       3. To upgrade, boot to the qualifying Windows desktop, insert the Windows 7 Upgrade disc in the DVD drive.
       4. When the setup menu appears, select Custom (advanced) to initiate a clean install procedure.

Windows 7 Home Premium full version, does not require a previous qualifying license, you can use it do a upgrade or clean install (which you can also do with the upgrade version, just that the upgrade version requires a qualifying operating system).

Another thing to note about the Upgrade version, due to the fact the original full version software and the upgrade version software together constitute a single software program, you will need to retain your copy of the prior version of the software program (including all media, manuals and the Certificate of Authenticity) in order to establish your eligibility for the upgrade license.

No, you cannot use Linux as a qualifying operating system, you need Windows XP or Vista to use the Windows 7 Home Premium upgrade (activated and installed).
