Windows 10: Cant use the boot menu because of a lost password.

I have a problem with my computer. Was trying to fix the flimmer on my screen, followed the instructions on the web but it got me to unable to access because of pincode error. Follow another instructions to get to the boot menu, got there but when i open the command pond it doesnt open but ask for a password that doesnt exist anymore. How can i restore when its locked by password? I have checked every option in the bort menu, all require password.

You can reset your password following the next steps:

• Reboot your computer / Turn your computer on.
• Hold down the Shift key at the start of the boot process to enable the GNU GRUB boot menu (if it does not show)
• Press ESC at the GNU GRUB prompt.
• Press e for edit.
• Use the Arrow keys to highlight the line that begins with kernel and press the e key.
• Go to the very end of the line and add rw init=/bin/bash
• Press Enter and then press b to boot your system.
• Your system will boot up to a passwordless root shell.
• Type in passwd yourusername
• Set your new password.
• Restart your system.

 

Lost My Administrator Password

To which "this" are you referring?
- If you are following the tutorial Bree suggested in the very first reply to your question then what you need to do at each step is explained in detail. So which step are you at?
- If you are following a different procedure then state what it is and which step you are at. If, for example, you are trying to manually enable the Built-In Admin as suggested in post #11 then that account has no password.

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.
