Check boot order: Ensure that your computer is set to boot from the correct drive. Go into the BIOS or UEFI settings and make sure the hard drive or SSD with Windows 10 is listed as the first boot option.

Understanding the Symptoms and Resolving the “Operating System Not Found” Error

If you encounter the “Operating System Not Found” error on your Windows 10 PC, there are a few steps you can take to resolve this issue.

First, try checking your boot sequence in the BIOS settings. Ensure that your hard drive is set as the primary boot device.

Next, make sure there are no external drives or USB media connected to your computer. Sometimes, these can interfere with the boot process.

If that doesn’t resolve the issue, you can try using the Command Prompt to fix any potential errors.

– Start by booting your computer from the installation media.
– At the initial screen, press any key to boot from the media.
– In the Windows Setup screen, press Shift + F10 to open the Command Prompt.
– Type “diskpart” and press Enter.
– Then, type “list disk” to see the available disks.
– Identify the disk containing your operating system and note its number.
– Type “select disk X” (replace X with the disk number) and press Enter.
– Finally, type “bootrec /fixmbr” and press Enter to fix the Master Boot Record.

Once you’ve followed these steps, restart your computer and see if the “Operating System Not Found” error has been resolved.

Troubleshooting Steps to Fix the Issue

Check the Boot Order in BIOS:
- Restart your computer and press the key specified to enter the BIOS settings (usually Del, F2, or F10).
- Navigate to the Boot tab and make sure the correct hard drive is selected as the first boot device.
- Save the changes and exit the BIOS.
Reset the BIOS to Default Settings:
- Access the BIOS settings as mentioned in the previous step.
- Find the option to reset the BIOS to its default settings.
- Confirm the reset and save the changes.
Check the Hard Drive Connection:
- Power off your computer and unplug it from the power source.
- Open the case and locate the hard drive.
- Ensure that the cables connecting the hard drive to the motherboard are securely connected.
- If necessary, disconnect and reconnect the cables to ensure a proper connection.
- Close the case and reconnect the power source.
Repair the Master Boot Record (MBR):
- Insert your Windows 10 installation media (DVD or USB).
- Restart your computer and boot from the installation media.
- Choose your language preferences and click “Next.”
- Select “Repair your computer” and then go to “Troubleshoot” > “Advanced options” > “Command Prompt”.
- In the Command Prompt, type bootrec /fixmbr and press Enter.
- Wait for the process to complete and restart your computer.
Rebuild the BCD (Boot Configuration Data):
- Follow the steps 1-4 in the previous repair method to access the Command Prompt.
- In the Command Prompt, type bootrec /rebuildbcd and press Enter.
- When prompted to add the installation to the boot list, type Y and press Enter.
- Restart your computer and check if the issue is resolved.

Disconnecting Peripherals and Restarting the PC

To troubleshoot the “Operating System Not Found” error on Windows 10, try disconnecting any external DVD drives or other peripherals connected to your PC. These devices could potentially interfere with the boot sequence and cause the error message to appear.

To do this, follow these steps:

1. Power off your PC.
2. Disconnect any external drives or peripherals, such as DVD drives or USB devices.
3. Wait for a couple of minutes.
4. Restart your PC.

After restarting, check if the “Operating System Not Found” error still persists. If it does, try other solutions such as scanning for errors using the installation media or accessing the command prompt with Ctrl+Alt+Del.

Remember, disconnecting peripherals and restarting your PC can help resolve the error, but it may not be the ultimate solution. If the problem continues, further troubleshooting steps may be required.

python import platform


def check_operating_system():

    operating_system = platform.system()

    if operating_system == 'Windows':

        version = platform.release()

        if version == '10':

            return 'Windows 10'

        else:

            return 'Windows (non-10 version)'

    else:

        return 'Non-Windows OS'

print(check_operating_system())

This code uses the `platform` module in Python to retrieve the current operating system and its version. It checks if the operating system is Windows and then verifies if the version is Windows 10. The function `check_operating_system()` returns the corresponding result. However, please note that this code solely checks the current environment where it is executed, and it requires access to the operating system.

Checking if BIOS Recognizes the Hard Drive

If you are encountering an “Operating System Not Found” error on Windows 10, it may be worth checking if your BIOS recognizes the hard drive. Here are the steps to do so:

1. Restart your computer and enter the BIOS settings by pressing the appropriate key during the boot process (usually F2 or Del).
2. Navigate to the “Storage” or “Drives” section in the BIOS menu.
3. Check if your hard drive is listed. If it is not, there may be an issue with the connection or the drive itself.
4. If the drive is listed but not recognized, try disconnecting any other drives that may be connected temporarily.
5. Save the changes and exit the BIOS.
6. Restart your computer and see if the “Operating System Not Found” error persists.

Remember to consult your computer’s manufacturer or documentation for specific instructions on accessing the BIOS.
