    No grub after boot-repair

    Hi community,

    I know variants of this question have been asked many times before, but instead of making some mistaking and having to do a clean reinstall (again), I am asking for assistance here.
    After installing Ubuntu 16.04 in dual boot with windows, I ran boot-repair and the following pastebin was created:

    Thanks in advance!

    Re: No grub after boot-repair

    And the problem? I am just curious. It is nice to know what the actual problem is.


    The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volumeread-only with the 'ro' mount option.
    That could be the cause of the problem.

    To install Ubuntu in UEFI mode:


    https://help.ubuntu.com/community/UEFI

    Ubuntu has been installed in EFI mode the same as Windows has been installed in EFI mode. That is correct action. But Windows is still in Fast Startup which is actually hibernation.

    Re: No grub after boot-repair

    In addition to Windows fast start up, HP is not particularly UEFI dual boot friendly.
    Most copy shimx64.efi to /EFI/Boot/bootx64.efi and boot a UEFI: hard drive entry.
    the bootx64.efi is a fallback or hard drive boot entry and is the same file name (different files) used to boot a Windows installer or Ubuntu's installer.

    HP Check if Customized UEFI settings available like this HP ProBook 4340

    HP Manually renamed files to make it work.

    You can run Boot-Repair's advanced mode:
    Boot-Repair now creates bkpbootx64.efi and copies shimx64.efi as bootx64.efi. This is a hard drive default or fallback boot entry in UEFI.
    'Use the standard EFI file' in advanced options.

    But that may not add an UEFI entry into NVRAM for booting hard drive.

    Also HP has its system maintenance .efi files in the ESP - efi system partition. Many other vendors have to files in hidden ESP or another efi type partition. But then Boot-Repair sees all those .efi files & adds them to the grub menu.
    You can delete most or all by editing 25_custom.

    # Edit 25_custom entries created by Boot-Repair:
    sudo cp -a /etc/grub.d/25_custom /etc/grub.d/bkp25_custom
    # turn off execute bit or it will run backup also
    sudo chmod a-x /etc/grub.d/bkp25_custom
    sudo nano /etc/grub.d/25_custom
    # Then do:
    sudo update-grub

    Re: No grub after boot-repair

    Thank you for the advice. Disabling fast start up and running boot repair with the "large ATA disk" option worked. I have about 10 entries in my GRUB panel now, but I ignore most of them and access ubuntu just fine. Thank you!
