Backup your hard drive: Create an image backup to an external USB hard drive so you are able to recover Windows 7 to its pre service pack 1 state should any problem occur either during or after the installation. You can use Windows 7’s Backup and Restore to create a “System Image” or a third part software application such as Ghost 15 or Acronis True Image Home 2010.
