Here are some steps to fix common Windows installation errors using the Command Prompt:

Basic Troubleshooting Steps

Restart your computer: Sometimes, simply restarting your computer can resolve issues related to system files or drivers.

Check for updates: Ensure your system is up-to-date with the latest security and feature patches.

Run the System File Checker (SFC): This tool scans and repairs corrupted system files. Run sfc /scannow in Command Prompt.

Common Errors and Solutions

“Network Connection Lost or Down” Error

– Check your network connection and ensure it’s stable.

– Try restarting the network adapter.

– If the issue persists, run netsh int ip show config to check for any issues with the Network Adapter settings.

Installation Issues:

* “This is not a supported operating system” error

– Ensure your system meets the system requirements of the operating system you’re installing.

– Try updating or reinstalling the operating system if necessary.

– Check if there are any conflicts with other software installed on your computer.

Installation Issues:

* “Installation failed” error

– Check the installation log files for any errors.

– Run sfc /scannow to check and repair corrupted system files.

– If none of the above steps resolve the issue, reinstall the operating system using a bootable USB drive or CD/DVD.

Advanced Troubleshooting Steps

Check Event Viewer logs: Run eventvwr.msc (for Windows 7 and later) to view error logs.

Run the System Restore Point: If you’ve recently installed an update, try restoring your system to a previous point using msconfig > Backup & Restore.

Check for conflicts with other software:

– Close all unnecessary programs.

– Run taskmgr.exe (for Windows 10 and later) to check for any resource-intensive programs running in the background.

Using Command Prompt Commands

To troubleshoot specific issues, use the following commands:

systeminfo: Displays system information and hardware specifications.

chkdsk: Check disk drive health.

dir /s : List files and folders recursively.

dir > output.txt: Output a detailed list of files and folders.

Example Command: To check for disk space usage, use:


dir /s C:\> dir | findstr ".*"

Replace C: with the root directory you want to monitor. This will display a list of all files and directories in that directory, including their size.
