How to Repair Windows 10 Without CD or USB in 7 Ways

If your Windows 10 computer is not functioning properly due to startup issues, system errors, or corrupted files, you may need to repair it to restore normal operation. While using a Windows 10 installation disc or USB drive is a common method, it’s not always available. Fortunately, there are several ways to repair Windows 10 without a CD or USB drive. In this article, we’ll explore seven methods to help you get your computer back up and running.

Method 1: Launch Startup Repair

One of the easiest ways to repair Windows 10 without a CD is to use the built-in Startup Repair tool. Here’s how to do it:

1. Press the power button as soon as the Windows logo appears, and repeat this process two more times to enter the Windows Recovery Environment.
2. Select your language and keyboard input, then click “Troubleshoot” > “Advanced options” > “Startup Repair”.
3. Follow the on-screen instructions to complete the repair process.

Startup Repair will automatically scan and fix common startup issues, such as missing or corrupted system files, damaged Boot Configuration Data (BCD), and more.

Method 2: Run System File Checker (SFC) Scan

If you suspect that some system files are missing or corrupted, you can use the System File Checker (SFC) tool to scan and repair them. Here’s how:

1. Press the Windows key X and select “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.
2. Type “sfc /scannow” and press Enter.
3. Wait for the scan to complete. If any issues are found, SFC will attempt to repair them automatically.

After the scan is finished, restart your computer and check if the problem has been resolved.

Method 3: Use BootRec Commands

If your computer fails to boot due to a damaged Master Boot Record (MBR) or Boot Sector, you can use the BootRec tool to fix the issue. Here’s how:

1. Press the Windows key X and select “Command Prompt (Admin)” or “Windows PowerShell (Admin)”.
2. Type “bootrec.exe” and press Enter to open the BootRec tool.
3. Type the following commands one by one, pressing Enter after each command:

 bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd 

These commands will attempt to repair the MBR, fix the boot sector, and rebuild the Boot Configuration Data (BCD).

Method 4: Perform a System Restore

If you have created a system restore point before the issue occurred, you can use it to repair Windows 10 without a CD. Here’s how:

1. Press the power button as soon as the Windows logo appears, and repeat this process two more times to enter the Windows Recovery Environment.
2. Select your language and keyboard input, then click “Troubleshoot” > “Advanced options” > “System Restore”.
3. Follow the on-screen instructions to select a restore point and complete the process.

System Restore will revert your computer to an earlier state, which may resolve the issue if it was caused by a recent change or update.

Method 5: Use Windows 10 Reset This PC

If none of the above methods work, you can use the “Reset This PC” feature to reinstall Windows 10 while keeping your personal files. Here’s how:

1. Press the power button as soon as the Windows logo appears, and repeat this process two more times to enter the Windows Recovery Environment.
2. Select your language and keyboard input, then click “Troubleshoot” > “Reset This PC”.
3. Choose whether to keep your personal files or remove everything, then follow the on-screen instructions to complete the reset process.

Note that resetting your PC will remove all installed applications and restore Windows 10 to its default settings.

Method 6: Create a Windows 10 Installation Media

If you don’t have a Windows 10 installation CD or USB drive, you can create one using the Media Creation Tool. Here’s how:

1. Download the Media Creation Tool from the Microsoft website.
2. Run the tool and select “Create installation media for another PC”.
3. Follow the on-screen instructions to download the Windows 10 ISO file or create a bootable USB drive.
4. Boot your computer from the installation media and select “Repair your computer” to access the recovery options.

You can then use the installation media to perform a clean install, upgrade your current version, or access the recovery tools.

Method 7: Use a Third-Party Recovery Tool

If all else fails, you can use a third-party recovery tool to repair your Windows 10 installation. Some popular options include:

• Recoverit Windows Recovery: Allows you to create a bootable USB drive and recover data from a corrupted Windows installation.
• EaseUS Todo Backup: Offers a variety of backup and recovery options, including system image creation and restoration.
• Acronis True Image: Provides comprehensive backup and recovery features, including support for disk cloning and incremental backups.

Keep in mind that using a third-party tool may require additional setup and configuration, and you should always create a backup of your important data before attempting any recovery process.

In conclusion, there are several ways to repair Windows 10 without a CD or USB drive. By using the built-in recovery tools, running system scans, performing a system restore, or utilizing third-party recovery software, you can troubleshoot and resolve various issues affecting your Windows 10 installation. Remember to always create a backup of your important data before attempting any recovery process to ensure the safety of your files.
