    No grub menu

    I have dual boot Windows and Ubuntu.

    When I start my computer, I cannot see the grub menu. However, I am able to select whether I boot Windows or Ubuntu using my keyboard (I know what the menu looks like, and what buttons to click, but I cannot see the grub menu). I have tried running Boot Repair, but I still cannot see the grub menu. How can I fix this?

    This is the message I got after running Boot Repair: http://paste.ubuntu.com/p/5P9ZhXqywT/

    Re: No grub menu

    Try changing the line
    Code:
    GRUB_TIMEOUT_STYLE=hidden
    to
    Code:
    GRUB_TIMEOUT_STYLE=menu
    in the file /etc/default/grub
    and rerun the sudo update-grub command.

    I have made this change, but I am still having the same problem. I cannot see the grub boot menu.

    This is the updated boot repair message: http://paste.ubuntu.com/p/5Bcdn7bsCN/

    Re: No grub menu

    I ran the command

    Code:
    sudo update-grub

    This is the output

    Re: No grub menu

    Grub still not showing after powering on the PC?

    Your grub entry in your second boot-repair report looks OK to me so I'm a bit surprised that it does not appear.

    There are a few things to try to see if it can be encouraged to appear:-

    • Change the default OS (GRUB_DEFAULT=0 or 1 or 2)
    • Re-install grub completely (either from a running session or from a live session)
    • Tidy your efibootmgr list

    I would be cautious about trying too much, it depends on your level of confidence.
    Grub is a sensitive soul sometimes.

    Try the answer here:
    https://askubuntu.com/a/1154020

    Or you could try uncommenting the line
    Code:
    #GRUB_GFXMODE=640x480
    and try a resolution you know works on your monitor.
    Just to see if the default grub resolution was not feasible for it.

    I think that I have misunderstood this thread.
    Grub is available for you to select an OS but the text does not appear on the screen?

    Is there some sort of video setting in your UEFI set-up which delays the activation of the monitor?

    Re: No grub menu

    I am using a laptop. I don't think there is a UEFI set-up which delays the activation of the monitor. I have used this laptop with dual boot for about three years now. I never had this problem until a couple of days ago, and I still have no idea why I cannot see the grub menu.

    My laptop displays the screen with the Lenovo logo. I used to see this screen before the grub menu opened. Now, I can no longer see the grub menu.

    Re: No grub menu

    I have fixed the problem by uncommenting the line

    Code:
    #GRUB_TERMINAL=console
    and running the command

    Code:
    sudo update-grub
