    There was just another HP user with the locked efi partition. That is an unusual issue which do do not know how it occurs nor a good fix. But Boot-Repair did not report the locked efi issue on your system.
    Just as a test can you edit a file name in your efi? As that seems to be the issue Boot-Repair has.

    grub-efi fails to install with Input/output error - locked efi

    If you cannot edit a filename, backup entire efi partition delete efi partition with gparted, create new efi partition in same place with gparted, set boot flag to make efi and restore files.

    Yann provided an updated version to the ppa repo. This fixed the menu problem. (Awesome!)
    (http://paste.ubuntu.com/5677086/)

    Now I cannot boot to windows, since the previous problem persists for booting windows via grub. Each grub menu item gives an error, such as
    file path: ... /File(\EFI\Microsoft\Boot)/File(bkpbootmgfw.efi) ...
    error: cannot load image.

    I think that I am nearly there!

    ...but I can get to Win8 via F9 on start-up; choose EFI file as boot device; choose EFI/Microsoft/Boot/bkpbootmgfw.efi.

    This menu entry in grub2's menu should be using the same file in the efi partition?

    menuentry "Windows UEFI bkpbootmgfw.efi" {
    search --fs-uuid --no-floppy --set=root C616-56DA
    chainloader (${root})/EFI/Microsoft/Boot/bkpbootmgfw.efi
    }

    Yes. Weird.

    Full error:
    Code:
    /EndEntire
    file path: /ACPI(a0341d0,0)/PCI(0,11)/ATAPI(0,0,0)/HD(2,c8800,82000,8342c12b8be64e4c,9e,b0)/File(\EFI\Microsoft\Boot)/File(bkpbootmgfw.efi)/EndEntire
    error: cannot load image.
    Error similar for "Windows Boot UEFI loader":
    Code:
    /EndEntire
    file path: /ACPI(a0341d0,0)/PCI(0,11)/ATAPI(0,0,0)/HD(2,c8800,82000,8342c12b8be64e4c,9e,b0)/File(\EFI\Boot)/File(bkpbootx64.efi)/EndEntire
    error: cannot load image.

    Some only boot with secure boot on, others boot with it on or off. Have you tried both?

    Disabling secure boot seems to have fixed it, as a workaround. Somewhere in between osprober, grub, chainloader and secure booting it goes wrong.

    Thanks for your essential and timely assistance.

    Glad you have it working.

    Must be something in the secure boot or UEFI modifications that make it more difficult for some computers that prevents secure boot.

    I agree, I also have the feeling that there are several types of SecureBoot, and that Ubuntu (Linux in general) is still not compatible with all of them.
