Windows Data Recovery After Receiving Error Informing Pci.sys File Is Missing Or Corrupt

Windows is a reliant GUI based system that can be used to perform various tasks. Having evolved greatly since its inception, the one thing that this powerful operating system cannot guarantee is that data will not be lost. That is why, it is recommended that users must maintain backup to be able to perform Windows data recovery. Otherwise, in such a situation, they have to opt for powerful software to perform the task. Let us take an example to understand this better.

On trying to start your Windows 2000 computer system, you get an error message similar to the following:

File is missing or corrupt: C:WinntSystem32DriversPci.sys

1 file(s) expanded.

9.Once the same is done, you can quit the Console by typing exit.

Inserting the installation CD in the drive, and restarting the computer.

Install Windows 2000, by pressing Enter on first option screen, and click 'Accept' on the License Agreement.

After this, the Setup detects installation and when it prompts you to repair, press R.

3rd Method: But in case the setup refuses to detect Windows installation, then you will need to reinstall the operating system. But, since this procedure removes all the data saved in that partition, you will have to recover partition data using the most recent backup.
