Windows 10: Deleted Operating System appearing in Windows 10's Boot Menu.

I had a dual boot PC with Windows 10 and Windows 7 installed. Recently I felt that I no longer require Windows 7 so thought of deleting it. I deleted Windows 7 from System Configuration and then formatted the partition containing Win 7. However, now I am noticing that the Startup tab in System Configuration shows Selective Startup instead of Normal Startup. And when I tried changing it to Normal Startup I found Windows 7 appearing in the Boot menu under the Boot tab, although I no longer have Windows 7. How do I fix this?

Boot up selections, how to delete menu

This is your problem (but says Windows 7 -- this image is from Google anyway)





And you don't want to see this menu again, right?

if so there's two ways.

One is to hide the Window, but it will remain hidden even if you install another OS:

Right Click "My Computer" > Properties > Advanced System Settings > Advanced > Startup and Recovery > Settings > Uncheck the "Time to Display list of Operating Systems", and click OK.

The other solution is to remove the old entry from the BootMenu:

Download and Install EasyBCD Beta 64 with Win7 Support.

Run EasyBCD > Add/Remove Entries > Manage Existing Entries > Remove the ones you don't want > Click Save.

That's it.

 

Unable to boot the operating system to desktop after the Anniversary Update on Windows 10

Hi,

Now that you have me with you let me take care of this.

Provide us additional information to assist you better with this issue:

• What is the make and model of your computer?
• What is the complete error message/ error code of this issue?

As a workaround I suggest you to unplug all the external devices connected to your computer, hard reboot the device and check with the status of this issue.

If the issue still persists, try the below troubleshooting steps as the boot files of current operating system might got corrupted.

I suggest you to download Windows 10 ISO file, create an installation media from other working computer to perform Startup Repair of the computer that you are unable to boot.

Using ISO file to perform Startup Repair will allow the device to boot the system to Windows Recovery Environment and tries to repair the device.

Step 1:
I suggest you to try Startup Repairing the Windows and check if it helps.

Download the Windows 10 ISO and create a Media Creation tool and then perform Startup Repair.

Refer to the following link: Installing Windows 10 using the media creation tool

(Refer to the section "Installing Windows 10 using the media creation tool” in the above article for creating the tool).

Step 2: After creating the tool perform Startup Repair.

I would like to inform that, if your Windows 10 is not able to boot or startup, Startup Repair will come into action and try to diagnose and fix the issue. It will scan system files, registry settings, configuration settings and
more and try to fix the problem on its own, automatically.

Perform the Startup Repair:

• When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be
  F12.
• The boot menu key might differ with each manufacturer. If you are unable to find the boot menu key, you may refer the user manual.
• Restart the computer, when the manufacturer's logo is displayed, keep pressing the
  Boot menu option key to enter the boot menu and change the boot option to
  CD\DVD ROM.
• After you boot your computer using Windows 10 DVD, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
• Select the correct time and Keyboard type.
• Click Repair your computer in the lower left corner
• Click on Troubleshooting, advanced option and then click
  Startup Repair.

Hope it helps. Kindly update the status of accessing/ booting the operating system for further assistance.

Thank you.

 

No startup boot menu

Hello Kimoefat,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

As an initial recommendation, I would suggest you to access the System configuration utility and check if the Operating System installation path for Ubuntu exists. To do so, follow the below steps.

• Type msconfig in the search bar and select System Configuration from the search results.
• Select the boot tab in the System configuration console to check if the installation path for Ubuntu exists.

If it exists, next logical step is to check if the boot menu time out has been set to 0, which results in Boot menu not showing up.

The boot menu time-out determines how long the boot menu is displayed before the default boot entry is loaded. It is calibrated in seconds. To change the boot menu time-out, use the Bootcfg
/timeout switch. Valid values are from 0 through 999. You cannot use Bootcfg to set an indefinite time-out.

You can run the following Run command line to set the boot menu time-out accordingly. To do so, follow the below steps.

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt
  
• 
  Type in the following command: bootcfg /timeout 10
  
  timeout 10 will set the time frame to 10 seconds
  

However, if the Boot path for Ubuntu does not exist in the boot menu of System Configuration utility, I would suggest you to check if the Ubuntu is overridden by the Windows installation or if the Ubuntu installation files are corrupted.

Hope the above information is helpful. If you need further information, feel free to write to us and we would be happy to help you.

Thank You.
