    SP314-51-376C is your exact model number.

    Did you make any changes in Windows that may have caused this?
    Did you install any new programs or apps recently that may have caused this?
    Did you make any changes in the BIOS?
  • Uefi mode is already native to this notebook model! So you do not see the boot mode! I know this, because only the uefi mode has the secure boot! Create an easy access password in setsupervisorpassword so you can disable secure boot! Make sure windows boot manager appears first at boot!
    If it does not appear, exit the bios and immediately press alt + f10 to try to install the factory windows!

    I did not make changes in my pc. But i did download an emulator for a game pubg mobile. Sometimes it made my pc lag. Not sure if that caused it tho.

    This method did not work for me sadly. 
  • OK! Did you check if windows boot manager is first in boot? Checked if hd is recognized in the information section?

  • Yes! Hd is recognized in both the information and boot sections! Try this:
    a) Activate the f12 boot mode function and press f10 to save when exiting. Then immediately press f12 and choose hd to boot!
    b) If it does not start with the above tip, restart the notebook and press alt + f10 to try to reinstall windows!

    Sadly....
  • OK! So I suggest you try these steps:
    a) enter the bios and press f9 to restore the bios to the default settings and then press f10 to save when exiting! Then check to see if it solves the problem!
    b) make a recovery pendrive using an iso of the microsoft: https://go.microsoft.com/fwlink/?LinkId=691209
