    BIOS Boot Options Missing


    Hi all,

    I am running Win 8.1 Pro on an ASUS laptop N56VJ that originally had Win 8. It was updated to 8.1 quite some time ago. In preparation to do a clean install of Win 8.1 I noticed that the only boot option listed is the windows boot manager.

    I've looked through other posts but do not see if this is critical to have the other boot options available. Is this normal to only have the windows boot manager shown? What steps should I take next?

    I tried the F9 key to "optimize defaults" but nothing changed.

    Attached are some pics of the BIOS and I also ran the disk management function.

    Thanks in advance,
    Bas

    Hi Bat 1,

    Thanks for your reply. I'm not sure if you noticed, there are no other boot options listed even when I turn off Secure Boot, Disable Fast Boot, and enable CSM & enable Launch PXE OpROM. See pic below.

    Do I need to be concerned about this?

    On the BIOS tab with Save & exit, there is an option to restore defaults, does anyone know if this could fix the boot options or do I need to create a new boot option.

    Thanks,
    Bas

    You shouldn't need to add a boot option, just insert the install USB or DVD and it'll find it on its own. You just need to change the boot order. uefi - If USB is not listed in BIOS as a boot option, does that mean the machine can't boot from USB? - Super User

    That is what it is called
    I noticed that the only boot option listed is the windows boot manager.
    Be it Bootmgr or Bootmgr.efi

    that bootmgr will invoke the BCD Info
