It seems like you are encountering an error related to the VirtDisk.dll file during your Windows installation. This issue might occur if the required file is missing or corrupted on the installation media. Here are some steps you can take to try to address this problem: 1. Verify Installation Media: - Ensure that the Dell Restore DVD is not damaged. Try cleaning the DVD to remove any smudges or scratches that might be affecting the installation process. 2. Check DVD Drive: - Verify that your DVD drive is working correctly. If possible, try the installation on a different computer to rule out any issues with the drive itself. 3. Alternative Installation Media: - If you have access to a USB drive, you can create a bootable USB drive with the installation files. This can sometimes be more reliable than using a DVD. 4. Download the VirtDisk.dll File: - Search online for the VirtDisk.dll file. Make sure to download it from a reputable source. You can place the file in the appropriate directory as suggested. 5. Extract Installation Files: - If the VirtDisk.dll file is required during the installation process, consider extracting the contents of the DVD to a USB drive or a local folder on your computer. This way, the setup may not need to access the DVD for all files. 6. Contact Dell Support: - If the issue persists, consider contacting Dell Support for further assistance. They may provide you with specific instructions or the necessary files to resolve the problem. Try the above steps to see if you can overcome the error and continue with your installation process.
