Factory Reset?

I've had this computer for a few months, and suddenly it starts showing me a No Bootable Device-- insert boot disk and press any key page. I've watched so many videos on how to fix it that I physically cannot even try anymore. 

I'm going to attempt a factory reset, but the keys I've been told to press don't get to where I'm suppose to be.

By the way, the computer is from the E5-576 series. My model number is N16Q2.

    Try booting into the recovery environment, if possible, and then performing a startup repair. To get into the recovery environment, turn your computer on and off three times.  While booting, make sure you turn off the computer when you see the Windows logo. 

    If you are unable to perform a startup repair, then your next option is to try using your Windows 10 installation media to fix the boot error.

    If you don’t have installation media, you will need to go to a working computer and Create Windows 10 installation media at https://www.microsoft.com/en-us/software-download/windows10. You can also go to a working Windows 10 PC and create a recovery drive.  When using a USB drive, make sure to set up your BIOS (press F2 or F12 on boot) to setup BIOS to boot from the USB drive.

    After booting into Windows 10 setup, choose the Repair your computer option (bottom left corner)


    Then on Troubleshoot choose either > Reset this PC  Option (to reset it completley)

    or  

    Advanced options (for Command Prompt) which is a different boot fixing process and method:

    Once you have the command prompt up on screen, you will need to issue a set of commands to find and resolve issues that might be preventing your computer from booting.

    Type BOOTREC /FIXMBR and hit <Enter>.

    This command will attempt to fix any corruption issues with the master boot record.

    If all goes well, you should see The operation completed successfully.

    Next, type BOOTREC /FIXBOOT then hit <Enter>.

    This command will attempt to write a new boot sector on the hard disk if Windows detects damage. Usually, this happens in cases where an older version of Windows was installed, or a non-compatible operating system such as Linux was installed.

    If you are seeing an error such as Boot Manager is Missing, then the BOOTREC /RebuildBcd command might be able to fix it. This operation can also restore boot entries for older versions of Windows if you have a dual boot configuration.

    If BOOTREC /RebuildBcd does not work, then Microsoft recommends you back up your BCD (Boot Configuration Data) store, then run the BOOTREC /RebuildBcd command again. Here is how you do it.

    Type each command then hit <Enter>:

    • bcdedit /export C:\BCD_Backup
    • c:
    • cd boot
    • attrib bcd -s -h -r
    • ren c:\boot\bcd bcd.old
    • bootrec /RebuildBcd

    Another option if you are dual booting with older versions of Windows such as Windows 7 is the BOOTREC /ScanOs command. The ScanOS command can find and restore entries for older versions of Windows.
