Windows 10 Crashed and Won’t Boot – 12 Fixes to Restart PC

Having your Windows 10 crash and refusing to boot can be frustrating. However, there are a few fixes that can help you restart your PC smoothly.

Boot in Safe Mode

To boot your Windows 10 PC in Safe Mode, follow these steps:

1. Start by shutting down your computer completely.
2. Turn on your computer and as soon as you see the manufacturer’s logo, press and hold the F8 key repeatedly.
3. This will bring up the Advanced Boot Options menu.
4. Use the arrow keys on your keyboard to highlight “Safe Mode” and then press Enter.
5. Windows will now start in Safe Mode, which only loads essential drivers and services.
6. In Safe Mode, you can troubleshoot and fix issues that may be preventing your computer from booting normally.
7. Once you’re done troubleshooting, you can restart your computer to exit Safe Mode and boot into Windows normally.

If you’re unable to access the Advanced Boot Options menu using the F8 key, you can also try the following method:

1. Insert your Windows installation media, such as a USB flash drive or DVD.
2. Restart your computer and press any key to boot from the installation media.
3. Select your language preferences, and then click “Next”.
4. Click on “Repair your computer” at the bottom left corner of the screen.
5. In the next window, select “Troubleshoot” and then “Advanced options”.

In Safe Mode, you can run CHKDSK to scan and fix any issues with your hard drive. To do this:

1. Press the Windows key + X and select “Command Prompt (Admin)”.
2. In the Command Prompt window, type “chkdsk C: /f” and press Enter. Replace “C:” with the drive letter of the partition you want to scan.
3. You’ll be prompted to schedule a disk check on the next restart. Type “Y” and press Enter.
4. Restart your computer for the disk check to run.

Remember to remove any USB flash drives or external storage devices before starting the boot process. Safe Mode only loads essential drivers, so any external devices may cause issues.
