My Tech Fundas: Tips and Techniques

When you start Windows, you receive an error similar to:

File is missing or corrupt: C:\Winnt\System32\Drivers\Pci.sys

When this happens you should restore the file using the Recovery Console or perform a repair installation of Windows.

To restore the file do the following:

1. Start the Recovery Console.

2. Select the installation you wish to access.

3. Type the administrator password.

4. Type MAP to determine the drive letter assigned to the CD-ROM.

5. Type Expand \i386\pci.sy_ c:\Winnt\System32\drivers /y. You should receive a message that says:

pci.sys

1 file(s) expanded.

6. Type exit and reboot.

*NOTE: c:\winnt should be replaced with the location of your Windows installation.
