This pesky error pops up during the booting process of your computer and prevents you from booting to your Windows 10 PC and displays the error message in a black screen instead. To fix this problem, here are some suggestions you need to check out.
Option 1 – Try checking the boot order in BIOS
- Turn on your PC and repeatedly tap the Setup key right away about once every second until you see the Computer Setup Utility or the BIOS settings.
- Then use the right arrow key to select the Security menu and then use the down arrow key to select the Secure Boot Configuration option and then tap Enter.
- Just a heads up, before you can use Secure Boot Configuration, a warning will pop up. Simply tap F10 to continue to the menu. After opening it, use the down arrow key to select Secure Boot and then the right arrow key to set the setting to Disable.
- Next, select the Legacy Support option using the down arrow key and then the right key to set the setting to Enable.
- Now tap F10 to confirm the changes and then use the arrow key to select File menu and then the down arrow key to select Save Changes and then Exit and tap Enter to select Yes. From there, your computer should restart and once it does, use the power button to switch it off.
If you are now able to boot from your hard drive, you need to know which option to choose once the boot menu pulls up. Refer to the steps below to easily boot from your hard drive.

Option 2 – Try running the DSKCHK Check from the Recovery Media.

- Then tap Accept to agree to the terms and conditions and then from the initial screen, select the “Create installation media (USB flash drive, DVD, or ISO file) for another PC” option. Keep in mind that the language, architecture, and edition of the bootable drive will be selected based on your PC’s settings but you have to uncheck the Use the recommended options for this PC in order to choose the correct settings for your own computer that’s getting the error.
- Now click Next and then click the USB drive or DVD option once prompted to select between USB or DVD depending on what device you are using to store this image on. Then click Next and select the required drivers from the list of storage devices currently connected to the computer.
- Click Next. After that, the Media Creation Tool will proceed to download the files needed to install and create the installation device.
- The next thing you have to do is to insert the installation drive.
- After that, you will see the “Choose your keyboard layout” window so select the one you prefer and then the Choose an option screen will pop up.
- Go to Troubleshoot > Advanced Options > Command Prompt. After opening Command Prompt, input the following command and hit Enter.
CHKDSK /R /X C:
- Now boot your PC without the recovery drive and check if the problem’s fixed or not.
Option 3 – Try resetting the BIOS
- Open the computer case and then look for the battery in the motherboard. If you can’t find it, you can seek out the motherboard or computer documentation of your PC as well as browse the web or contact manufacturer for further assistance.
- Removing the battery should be easy especially if your computer uses a coin cell battery. Just use your fingers to grab on the edge of the battery then pull it up and out of the socket that’s holding it in place.
- Keep the battery removed for about 10 minutes and then insert it back and try booting into the BIOS.
Option 4 – Try using the Startup Repair

- Select the keyboard layout from the Choose your keyboard layout window.
- From there, the Choose an option screen pops up. Navigate to Troubleshoot > Advanced Options > Startup Repair.
