    [SOLVED] Black graphical boot menu disappeared

    Good afternoon:

    Lately, (since version 20.04) I am having occasional problems especially with the installation. I just reinstalled version 22.04 LTS and the black graphical boot menu (Kubuntu, testmemory, safe mode, etc) has disappeared, just the O.S boots directly.

    The O.S is installed in UEFI mode and these are the existing folders in the /sys/firmware directory:
    /acpi, /dmi, /efi and /memmap.

    Is there any way to recover it? I would appreciate any indication on this matter. Thanks in advance and sorry for my poor english.

    Memtest only works on older Legacy BIOS boooting, not UEFI systems, so you can't get that unless you can swtich your boot mode.

    You should be able to get a menu (iirc) by stabbing esc (maybe shift) during bootup, just past the POST as as you power on

      Thank you for your answer.
      Yes, esc worked. Is there any way to make it permanent and have it always show up when booting the O.S?. It gives me more confidence.

        You can edit the grub configuration as described here:

        Or try the tool grub-customizer

          The article is correct, but in my case it didn't work until I also increased the GRUB_TIMEOUT variable to 7, otherwise it didn't seem to give it enough time to display on the screen. To keep in mind.

          Thanks.

            If you want the grub menu to remain displayed until you actually press Enter, then change the value of GRUB_TIMEOUT to a negative value.
