Grub2 working, but not visible

kw flag

I just did a fresh dual boot installation of Windows 10 along with Ubuntu 20.4 LTS. Grub2 seems to be working fine, but simply isn't showing up. Instead, it just states "booting in insecure mode" or something of that sort.

I know that grub2 is working because if I immediately press enter, it boots in Windows (just as I customized it with Grub Customizer) and if a reboot and then on the same screen I press down and then enter, it boots in Ubuntu, just as desired.

So, everything works, except I can't see the menu. I've reinstalled Ubuntu, tried reinstalling just grub (can't figure that out). Any ideas?

This sounds like something you did with GRUB customizer. From your description, it's behaving as you programmed it. Are you sure that anything is actually wrong? IMO customizing GRUB doesn't provide any tangible benefits and you risk bugging out your boot.

You may have problems with the graphics. Disable the graphical terminal like this: Remove the `#` character from the relevant line: `sudo nano /etc/default/grub` and make the line into `GRUB_TERMINAL=console`; Save the file, run `sudo update-grub` and reboot.

@guiverc Sorry, I fixed the tag.

@Nmath It was a problem before I used customizer. I was hoping that customizer would fix it, but nothing changed. Customizer even has an option to toggle visibility at start up, and it was on by default.

I suggest you edit /etc/default/grub (as superuser) and add GRUB_TIMEOUT_STYLE=menu. You can also play with GRUB_DEFAULT and GRUB_TIMEOUT to suit your needs.

NB: After editing this file, you MUST run update-grub (also as root). In a terminal, type sudo update-grub to do so.

Good luck :)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
