Before diving into the steps, ensure you have administrative access to your computer. It’s also advisable to back up any critical data to avoid potential loss during troubleshooting. No specific software downloads are required, but familiarity with Windows settings and command prompts will be beneficial.
Step 1: Restart Your Computer Multiple Times
The first step involves a simple yet effective restart procedure. This can help reset temporary configurations that may be causing the error. Here’s how:
- Turn off your computer by holding the power button.
- Wait a few seconds, then turn it back on.
- As soon as the system starts, turn it off again using the power button.
- Repeat this process three times.
- On the fourth boot, you should see a message indicating that your PC did not start correctly.
Step 2: Access Advanced Recovery Options
Once you reach the recovery screen, you will need to navigate to the Advanced options. Follow these steps:
- Click on Advanced options.
- Select Troubleshoot.
- Click on Advanced options again.
- Select Command Prompt. If you do not see this option, go back and select Recovery options until it appears.
Step 3: Repair Boot Configuration
In the Command Prompt, you will enter several commands to repair the boot configuration. Type each command followed by Enter:
bootrec /fixmbr
This command repairs the Master Boot Record.
bootrec /fixboot
This command writes a new boot sector onto the system partition.
bootrec /scanos
This command scans for installed Windows operating systems.
bootrec /rebuildbcd
This command rebuilds the Boot Configuration Data.
Step 4: Check for Corrupted System Files
Next, you should scan for and repair any corrupted system files. In the Command Prompt, type the following command and press Enter:
sfc /scannow
This process may take some time. Allow it to complete and follow any instructions on the screen.
Step 5: Run a Disk Check
After repairing system files, it’s important to check your disk for errors. In Command Prompt, enter the following command:
chkdsk C: /f /r
This command checks the C: drive for errors and attempts to fix them. You might be prompted to schedule this for the next system restart; type Y to confirm.
Extra Tips & Common Issues
While performing these steps, be mindful of the following:
- Ensure your system is plugged into a reliable power source.
