GRUB menu is not shown after Xubuntu 18.04 update

Zeta.Investigator

I'm on a dual-boot setup (Windows 10 + Xubuntu 18.04). It was working fine until I left Xubuntu without updates for 2 months.
Then, after update, the grub menu for selecting OS is no longer shown. Also, the boot process is taking longer now. Sometimes even it hangs on "Lenovno" logo after POST.
Then I did a sudo update_grub:

[sudo] password for user:

Which didn't fix the issue. Here is my /etc/default/grub:

Note that I've updated Xubuntu not Windows 10 so I don't think windows has messed up with it.

Are you aware that *flavors* of Ubuntu only come with three years of supported life (five years applies to Ubuntu Desktop, Ubuntu Server but not flavors), so you're asking about a release that in April reached it's EOL. (https://fridge.ubuntu.com/2020/08/14/ubuntu-18-04-5-lts-released/ or a UWN - https://wiki.ubuntu.com/UbuntuWeeklyNewsletter/Issue681#Lubuntu_18.04_LTS_End_of_Life_and_Current_Support_Statuses highlights the EOL notices for Lubuntu/Ubuntu-MATE/Kubuntu/Ubuntu-Budgie; Xubuntu didn't announce EOL but refer https://xubuntu.org/release/18-04/ you'll see it's 29 April)

Check your boot process in your BIOS. Is your PC really booting the Xubuntu boot loader or is it the default windows version.

@rm- Can a ubuntu update change BIOS settings? I literally didn't do anything except `sudo apt update && sudo apt upgrade`

Need to see your /boot/grub/grub.cfg file. Not all of it, just all of the first menu entry (for Xubunti) down to its closing brace. Also need to see output of `sudo parted -l`

The only thing I can suggest that sometimes causes an issue is the 'GRUB_TIMEOUT_STYLE=hidden' which should be changed to `=menu`. Else I can't see any other issue with your grub file. Change it in `/etc/default/grub` and save, then `sudo update-grub` and reboot to see if it makes any difference. Try this first.

@Zeta.Investigator. Yes there are BIOS updates available via Linux. I was more thinking on a Windows BIOS update who might have messed things up for you.

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.
