Thus, this comprehensive article from tools will present you with multiple practical methods to assist you in fixing the Windows 10 won't boot issue and gaining access to your desktop.

Tip
Before beginning, it's advisable to ensure that peripherals such as the power supply, external devices, CPU, GPU, RAM sticks, etc., are correctly installed in your computer. If the boot issue is due to a loose connection, you won't need to follow the methods below.

Method 1: Troubleshoot in Safe Mode

Booting into Safe Mode only loads essential components and programs on your computer. This enables you to identify and address the problem in a protected environment. If you're unable to start Windows but can access Safe Mode, it indicates that something is loading and impacting your system during the boot process. This could be a virus, malware, or corrupted programs, among other things. Follow these steps to enter Safe Mode and rectify any issues.

Step 1. Turn your PC on and off 3 to 5 times while you see the Windows 10 loading screen to access the Windows Recovery Environment.

Step 2. Go to "Troubleshoot" > "Advanced options" > "Startup Settings" > "Restart," and press "4" or "F4" to access Safe Mode.

Step 3. Once in Safe Mode, identify the issue and fix it.

    • If you installed a program before the computer became unbootable, try uninstalling it to see if that resolves the issue.
    • If you installed any drivers prior to the system malfunction, update or roll back the driver to address compatibility problems.
    • If it's a result of a virus or malware infection, run an antivirus program to scan and fix the problem.

Method 3: Restore the System

Another efficient approach is to execute a System Restore. The condition for this is that you have previously created a restore point or have enabled your computer to create them automatically. System Restore allows you to revert your system to a previous state when it was functioning correctly. Hence, whether it's a failed update or a corrupted system file, performing System Restore will roll back your files, drivers, settings, and so on, to the last restore point. Please follow the guidance below to restore your system.

Step 1. Press "F11" while booting to enter the Windows Recovery Environment. (The hotkey may vary depending on the computer.)

Step 2. Select "Troubleshoot" > "Advanced options" > "System Restore."

Step 3. Wait for a moment, and your computer will display the System Restore interface.

Step 4. Choose your administrator account and enter any passwords if required. Then, click "Continue" to proceed.

Step 5. Click "Next" and choose an available restore point to undo the changes. Then, click "Next" to proceed. ("Scan for affected programs" will display which programs installed after the restore point will be removed.)

Step 6. Confirm the restore point and then click "Finish" and "Yes."

Method 4: Run the SFC and DISM Commands

The System File Checker (SFC) command line tool can scan Windows Dynamic Link Library (DLL) files and other crucial system files. If any issues are found, it will replace them. Additionally, when the SFC is unable to repair errors, you can utilize the Deployment Image Servicing and Management (DISM) tool. DISM can检查并修复Component Store Corruption. Here are the steps to run the SFC and DISM command lines: 1. **Running SFC:** - Press `Win + X` to open the Quick Access Menu, then choose 'Command Prompt (Admin)' or 'Windows PowerShell (Admin)'. - In the elevated command prompt, type: ``` sfc /scannow ``` - Press Enter and wait for the process to complete. This may take some time. 2. **Running DISM:** - If the SFC scan doesn't resolve the issue, proceed with the DISM scan. - In the same elevated command prompt, type: ``` DISM /Online /Cleanup-Image /RestoreHealth ``` - Press Enter and let the operation finish. This might also take a while as it needs to download updates from Microsoft's servers. After both scans have completed, restart your computer. These commands should help in repairing corrupted system files.

Step 1. Press "F11" while it's booting to enter the Windows Recovery Environment. (The hotkey may vary depending on the computer.)

Step 2. Select "Troubleshoot" > "Advanced options" > "Command Prompt."

If you encounter issues with your computer booting into the system after installing a previous version of Windows, unauthorized software, or certain graphics cards, you may need to disable Secure Boot.
