System hangs with a black screen and a blinking cursor after installing or upgrading Rescue and Recovery when using Sophos SafeGuard Easy

The computer cannot boot into Windows. The system hangs with a black screen and a blinking cursor. No messages are displayed on the screen.

Installing or upgrading the Rescue and Recovery application will update the master boot record (MBR). On the next boot, the Sophos SafeGuard Easy application might report that the MBR has changed and prompt the user to either allow the change or to undo the change. Users should allow the change. If these changes are not applied, the computer might not be able to successfully boot into Windows.

Affected configurations

Any system running Microsoft Windows 2000 or XP configured with Rescue and Recovery and Sophos SafeGuard Easy
