What do I do when my laptop gets formated and it doesn't boot any more.It keeps showing me install windows error

If your laptop is not booting after being formatted and you are encountering an "install windows error" message, here are some steps you can take to troubleshoot the issue:

1. Check your boot settings: Ensure that the correct boot order is set in your computer's BIOS or UEFI settings. Make sure the hard drive or SSD on which you have installed Windows is selected as the primary boot device.

2. Verify the installation media: If you are using a DVD or USB drive to install Windows, make sure it is not corrupted. Try using a different installation media or create a new one.

3. Check hardware connections: Ensure that all hardware components, including the hard drive or SSD, are properly connected. If necessary, disconnect and reconnect them to ensure a secure connection.

4. Run diagnostic tests: Many laptops have built-in diagnostic tools that can help identify hardware issues. Access your laptop's diagnostic tools (usually by pressing a specific key during boot) and run tests to check the health of your hardware.

5. Repair/Reinstall Windows: If none of the above steps work, you may need to repair or reinstall the Windows operating system. To do this, you will need a Windows installation media. Follow the on-screen instructions to repair or reinstall Windows.

6. Seek professional help: If you are not comfortable performing the troubleshooting steps yourself, or if the issue persists after trying the above steps, it may be best to seek assistance from a professional computer technician.

Note: Before attempting any troubleshooting steps, ensure you have backed up any important files and data from your laptop, as they may be lost during the process.
