Installing Windows 7 on some computers is not a simple task, especially if compatibility and support problems exist. According to
Microsoft,
Windows 7 fails to play nice with machines that have an AMD/ATI Radeon graphics processing unit (GPU) leveraging the embedded DisplayPort (eDP) technology. Customers that attempted to install Windows 7 on such computers found that they were unable to complete the deployment.
“When you install Windows 7 on the computer, a black screen is displayed during the installation process. However, the installation is still running. In this situation, you may be unable to complete the installation. If you have multiple displays, only the primary screen is black when you encounter this issue,” Microsoft explained.
