Lot many times you must have faced situations where your Windows-based computer system does not start. At times, such instances are cause of corruption in some system files. You can restore these files using some in-house corrective methods. In case, these methods do not bring normalcy to the computer and it remains inaccessible, then I would recommend using a third-party data recovery software to perform data recovery of the trapped data...
Let us take a practical example in which you are unable to start your Windows 2000 computer. The following error message is displayed:..
"File is missing or corrupt: C:\Winnt\System32\Drivers\Pci.sys"
The root cause of this problem, as displayed in the message, is that the PCI.SYS file is corrupt or missing.
To resolve this situation, you should perform the following methods:
- Restore Pci.sys from Recovery Console: You should try to restore the file from the Recovery Console using the following steps:
- Start the system using the Windows 2000 Setup CD. For this, you will have to define the BIOS settings to accordingly.
- Press 'R', when the 'Welcome to Setup' screen is displayed, to start the system in Recovery Console.
- Type 'map' and press the 'Enter' key. And note the drive letter given to the CD-ROM drive.
- Enter the following command in the command prompt and press the 'Enter' key.
expand drive:\i386\pci.sy_ c:\winnt\system32\drivers /y
drive: The drive letter of the CD-ROM
c: The drive on which Windows is installed
winnt: The folder in which Windows is installed
- When the file is copied, the following confirmatory message is displayed:
1 file(s) expanded.
Type 'exit' to quit Recovery Console and restart the system.
Perform an in-place upgrade to restore the file: If the previous method does not solve your problem, then you should try to reinstall Windows 2000. However, you may lose some of your customized settings. For this, you should perform the following steps:
Start the system using Windows 2000 CD.
Press the 'Enter' key to start the process to install a copy of Windows 2000.
Click 'Accept' to accept the License Agreement.
Press 'R' to start the Windows 2000 repair process. However, please note that this process takes the same time as the time taken during Windows fresh installation.
If the system still remains inaccessible, then you should use a third-party data recovery software to get back the data. Non-destructive nature and ease of use are some of the prominent feature of such data recovery tools.
