I wanted to install linux on my Predator Triton 300 (Predator PH315-52-79JK) and I messed up.

So I install Linux incorrectly and when it launches it stuck. For fix this I need to edit some files. And for this I need to boot with USB stick. 
But I can't. In UEFI there is 4 options
  • Linux (doesn't work)
  • GRUB - boot loader (can only boot into Linux and Windows)
  • Windows (write that booting files are broken)
  • UEFI shell (my last hope)
Also I can't get in advanced settings to set USB stick as default option to boot, when I press F10 or click on it, there is only "_" in top left corner.
Maybe it will be fixed if I update UEFI from UEFI shell or boot Windows installer and then update UEFI, but I don't how to boot from it.

P.S. I have password on UEFI. What if I enter incorrect password several times. Will it reset settings to default or just make a brick from laptop?

  • First, do this:
    a) access windows, press windows + r and type msconfig;
    b) then, go to system startup and enable safeboot;
    c) restart windows;
    d) access the bios, go to the MAIN tab, press CTRL + S and change the sata mode to AHCI.

    Then, convert the usb stick to gpt and format it in fat32:
    diskpart
    list disk
    sel disk x
    clean
    convert gpt
    create partition primary
    format fs=fat32 quick
    assign
    Then, extract the linux iso to the root of the usb stick.

    In the bios, create a password on setsupervisorpassword to disable secureboot.

    I can't boot into Windows, when I try to do it Windows show blue screen and write INACCESSIBLE_BOOT_DEVICE

    That's all I've got. Again: I can't get into advanced settings

    The same as laptop keyboard.
  • This can occur when the user installs linux. Can you disconnect the ssd and connect it to another computer, to remove the linux partitions?

    Maybe there is easier solution, I don't want to disassemble it.

    In any menu, you can load default settings by pressing F9. You can also press F10 to save any changes made and exit the BIOS Setup Utility.

    Press f9 to restore the bios and then f10 to save and exit.

    I did it and nothing happens :/
  • The best option is to disconnect the ssd:
    Disconnect the lition battery before removing the ssd.
    Then, check if the advanced functions of the bios can be accessed again.
