    So I've changed the laptop from EFI to BIOS using the assing button during the startup and now it just says: Operating System Not Found.

    How can I enter the Bios again? The assist button doesn't work and I've tried all the F buttons.


    Thanks!

    Did you flash bios or just change UEFI to Legacy in bios?

    I didn't flash the bios, just went to the EFI through the assist button and changed it to bios, and now I'm stuck

    If you just changed UEFI from Legacy through bios, then go back to bios and change it back unless you can't go to bios.
    If your laptop comes with Windows 8 by default, you have to push assist button. Otherwise, you can hold F2 while turn on your laptop.
