New in Windows 7 is the ability to create a system repair CD that will help you recover your computer from serious errors preventing windows from starting up. The recovery disc is based on Windows PE and includes the standard recovery options that are found on any Windows 7 installation disc.
If you have a Windows 7 installation disc, that doubles as a repair disc so you don’t need another. This article is only useful for users that have Windows 7 pre-installed and did not receive the installation media with their computer.
Creating the disc is very simple. Just click on the start button and type in resdisc and press Enter.
