    Question Installed Ubuntu 19, can't find in boot menu

    I'm trying to dual boot ubuntu and windows 10.

    Have already googled this a bit:

    https://ubuntuforums.org/showthread....7#post13341757

    The thread above mentions "Select an UEFI file as trusted for executing:" press ENTER
    I don't have such a feature in my BIOS.

    BIOS name:
    Brand American Megatrends Inc.
    Version R02-A1
    Date 9/01/2017

    Tried installing the boot-repair tool but it gave an error (booted up ubuntu on a usb).

    Acer motherboard (Acer Aspire GX-781(KBL) (U3E1))

    Re: Installed Ubuntu 19, can't find in boot menu

    You have an Acer and they require on newer (UEFI) machines that you set trust in the BIOS firmware before you can install any OS other than windows. In order to do this, you first need to set a Supervisor password in the BIOS firmware. Did you read the Ubuntu documentation on dual booting with windows 10, link below?

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

    Go back to the boot repair page and look at the 2nd option near the top of the page, using the ppa option . You should be able to do this while booted into the Ubuntu install usb. After doing this, there is no reason why you would reboot, just run boot repair and select ONLY the option to Create BootInfo Summary and post the link you get when it finishes here to get help.

    Other users with an Acer and how they set trust.
    Acer Trust Settings - details, some now report that then secure boot has to be on to set trust, never lose password:

    Using the code snippets at this site:
    HTML Code:
    https://help.ubuntu.com/community/Boot-Repair
    Code:
    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update 
    sudo apt-get install -y boot-repair && boot-repair
    I'm getting this error message when trying to run boot repair

    Re: Installed Ubuntu 19, can't find in boot menu

    After you set the supervisor password, did you look for some option to set 'trust'. I don't have an Acer so no way to check, might try an online search specifically for that.

    Not sure why you are getting the error with boot repair. Are you using the Ubuntu install DVD/USB to do this?

    Yes, but I couldn't find anything. I'm guessing my issue is somewhat similar to the one this person had:

    I used the same USB i used to install Ubuntu.

    I also updated my BIOS in case that would change anything. It didn't.

    You say Ubuntu 19, what exact version are you installing?
    Boot-Repair should work with any current version of Ubuntu, but does not work on EOL - end of life versions.

    After you update UEFI, it often sets many of the settings you changed back to defaults. Have you reset those settings?

    Post this from live installer:
    sudo efibootmgr -v

    Re: Installed Ubuntu 19, can't find in boot menu

    Update:
    I got Ubuntu to work, it now starts up automatically on boot

    Used this to get it working (typed in windows cmd):
    Code:
    bcedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi
    My BIOS/UEFI still looks the same and ubuntu isn't seen there as an option even if it does boot up if I touch nothing.

    Problem is:
    Now I can't boot to Windows.
    I get to the Grub screen, where the options are (about):
    Ubuntu
    Advanced Ubuntu
    Windows Boot Manager
    Windows Boot Manager 2
    System check

    If I select Ubuntu, it boots without a hitch.

    Both the Windows Boot Manager selections, however, only make the screen blink. Nothing else happens. If I want to boot anywhere, I have to boot into Ubuntu.

    Any way I could fix this?

    Here's the code output from
    Code:
    sudo efibootmgr -v
    :

    Code:
    BootCurrent: 0001Timeout: 1 seconds

    I've never used the bcdedit command you posted so I'm not sure what it is supposed to do but, looking at the efibootmgr output, it appears to be pointing to the Ubuntu efi files in the entry for Windows Boot Manager.

    Boot0001* Windows Boot Manager HD(1,GPT,3eb99d51-cc22-47b6-bc8b-96b71e2fb71e,0x800,0x32000)/File(\EFI\ubuntu\grubx64.efi)WINDOWS..
    Have you run sudo update-grub since making this change? If not, try that and post back what happens on reboot.

    Re: Installed Ubuntu 19, can't find in boot menu

    Years ago when UEFI was new we used to use a setting like that. But it caused issue and we have other better work arounds.

    If you use the Windows setting, Windows updates will overwrite it and you cannot boot Ubuntu.
    And grub only boots working Windows. So if Windows turn fast start up back on with an update or needs chkdsk, you have no way to boot Ubuntu.

    Now the most common work around is to use the fallback or hard drive boot entry in UEFI to be for Ubuntu.
    Examples in link in my signature.
