If Windows fails to start or it does not run normally, you can recover your computer by using the Symantec Recovery Disk CD. The drivers that are included on the recovery disk must match the drivers that are required to run your computer’s network cards and hard disks.
To help ensure that you have the drivers that you need to recover your computer, you can use the Run Driver Validation tool available on the Symantec Recovery Disk. The driver validation tool compares hardware drivers on the Symantec Recovery Disk CD with the drivers that are required to run your computer’s network cards and hard disks.
You should run the driver validation test any time you make changes to the network interface cards or storage controllers on a computer.
