Windows NT Emergency Repair Disk

Although Windows® NT is a very stable operating system, occasional software corruption may prevent the operating system from loading. Software corruption may result from any of the following: software and/or hardware installation, virus infection, loss of power while the computer is running, etc. The Windows® NT Emergency Repair Disk allows you to recover from near catastrophic software failure. Using the Emergency Repair Disk, a minimal implementation of the Windows® NT registry may be restored. In many instances, an operating system reinstall is avoided. You may create and update an Emergency Repair Disk using the RDISK.EXE utility included with Windowsâ NT.

The Emergency Repair Disk provides options for inspecting the boot sector, startup environment, system files, and portions of the registry.

Note: The Emergency Repair Disk replaces the current registry files with an older backup copy. As a result, some user settings may be lost, and it may be necessary to reinstall certain programs.
