Run the Windows 7 setup from the current version of windows (i.e.Windows Vista) if you think of upgrading. However, if you’re planning to do a clean install, I recommend that you back up first, then boot from the Windows 7 DVD and wipe out any existing partitions so there’s nothing left but unallocated space. The reason behind is that on a bare hard drive Setup creates a 100MB boot partition for holding boot files and for preparing the system for BitLocker drive encryption. That will save your some time and configuration hassles, if you plan to test BitLocker later.

It can wipe out any  data so be sure you have saved all important data before you start this. Also, you should not use this technique if your hard disk contains recovery or diagnostic partitions that you might want to use later. However, if you want to completely erase the disk and make a clean install than boot from the Windows DVD and follow the prompts to choose a Custom (advanced) installation, then click Next to get to this screen (the arrangement of disks will be different on your PC, but the principles are the same).

But if you want to upgrade it from the current windows than you can upgrade Windows Vista or Windows 7 Build 7077 or later. You cannot run x64 Setup on a system running an x86 build of Windows, or vice-versa. Be sure that you cannot upgrade Windows XP or any pre-7077 build of Windows 7 unless you make some hardware changes. You can install Windows 7 on the same volume as an existing Windows version. You cannot make any changes to the layout of a disk; you must use existing partitions, and Windows 7 Setup will not recognize unallocated space.

If you start from Windows7 Set up, you cannot upgrade an existing Windows version. Your only option is a custom install. You can delete existing partitions, create new partitions, extend an existing disk partition to unallocated space, or designate a block of unallocated space as the setup location. You can runWindows7 set up on the same volume as an existing Windows version.

In addition, there’s a subtle but significant difference between the initial screens, depending on how you start Windows7 Setup. If you launch Setup from within Windows, you can run a compatibility check.
