Making a Windows XP Install Drive

1. 
   1
   Create or Obtain A Windows Vista/7 ISO. Install a free burning program. There are a number of free burning utilities available online. You need one that can create ISO files. If you received your Windows 7 as a downloadable ISO file from Microsoft, you can skip to Step 2.
   • Insert your Windows 7 DVD. Open your new burning program. Look for an option such as “Copy to Image” or “Create Image.” If prompted, select your DVD drive as the source.
     
   • Save your ISO file. Choose an easy to remember name and location for the file. The ISO you make will be equal in size to the disc you are copying. This means it can take up several gigabytes of space on your hard drive. Be sure you have enough storage available.
     
   • Creating the ISO can take a long time, depending on the speed of your computer and DVD drive.
