Grub not showing despite being set to not hidden

RancidRandy · 2024-10-24T10:32:23.115Z

I have dualboot bluefin and bazzite on separate ssds. the setting is the same on both distros (not hidden) but in both cases I do not see grub menu when booting up Running ujust reconfigure-grub doesn't change anything

give us your

HikariKnight•10/24/24, 8:13 PM

is this a desktop?

H

HikariKnight•10/24/24, 8:15 PM

you can increase the timeout from 5 seconds to something higher then do

ujust regenerate-grub

ujust regenerate-grub

ujust regenerate-grub

ujust regenerate-grub
might be that it is showing up but it boots the default option by the time it is displayed on the monitor

R

RancidRandyOP•10/24/24, 9:23 PM

yeah its a desktop. just increased the timeout to 15, no change

H

HikariKnight•10/24/24, 10:00 PM

do you have multiple monitors attached?

H

HikariKnight•10/24/24, 10:01 PM

i know some people use the machine as a htpc and dont always have all monitors on, the grub menu might appear on one that is off

H

HikariKnight•10/24/24, 10:01 PM

other than that i dont really know why it does not show up for you

L

Linus Xu•10/24/24, 10:34 PM

Or it also is possible that your firmware directly loads the kernel…

L

Linus Xu•10/24/24, 10:35 PM

What’s your current boot order?

R

RancidRandyOP•10/25/24, 9:00 AM

yeah it has multiple monitors, i will try booting with just one plugged in

R

RancidRandyOP•10/25/24, 9:01 AM

current boot order is
-bazzite
-bluefin

R

RancidRandyOP•10/25/24, 9:01 AM

I will also try swapping the order and changing bluefin timeout to see if that makes any diff

R

RancidRandyOP•10/25/24, 9:17 AM

ok so:

i tried with individual monitors plugged in, no change. when i swapped the boot order from bazzite > bluefin TO bluefin > bazzite, the grub appeared when booting up bluefin. it only showed the bluefin os trees, so i ran

ujust reconfigure-grub

ujust reconfigure-grub

ujust reconfigure-grub

ujust reconfigure-grub and rebooted. after reboot, the grub did not appear.

I switched the boot order back to bazzite>bluefin, and on first boot the bazzite grub showed up, but only with bazzite os trees. I will try running the reconfigure grub command again but i imagine it will have the same effect

L

Linus Xu•10/25/24, 1:41 PM

Hmmmm I would say try checking your

/boot/grub2/grub.cfg

/boot/grub2/grub.cfg

/boot/grub2/grub.cfg

/boot/grub2/grub.cfg on both bluefin and bazzite

M

MingTheMerciless•10/25/24, 4:00 PM

I have the same problem. Grub doesn't show up during boot.
Bazzite runs in desktop mode and is the only operating system. Grub is set to 'Not Hidden'.

/etc/default/grub

/etc/default/grub

/etc/default/grub

/etc/default/grub looks identical to the one above.

MingTheMerciless•10/25/24, 4:10 PM

/boot/grub2/grub.cfg

/boot/grub2/grub.cfg

/boot/grub2/grub.cfg

/boot/grub2/grub.cfg:

terminal_output console
if [ x$feature_timeout_style = xy ] ; then
  set timeout_style=menu
  set timeout=5
# Fallback normal timeout code in case the timeout_style feature is
# unavailable.
else
  set timeout=5
fi

terminal_output console
if [ x$feature_timeout_style = xy ] ; then
  set timeout_style=menu
  set timeout=5
# Fallback normal timeout code in case the timeout_style feature is
# unavailable.
else
  set timeout=5
fi

terminal_output console
if [ x$feature_timeout_style = xy ] ; then
  set timeout_style=menu
  set timeout=5
# Fallback normal timeout code in case the timeout_style feature is

else
  set timeout=5

  set timeout_style=menu
  set timeout=5

This is probably the correct section.

Linus Xu•10/25/24, 6:47 PM

Both fives are 0 on my device with grub hidden so this part is correct

Linus Xu•10/25/24, 6:54 PM

Just checked that grub menu is showing when I choose to unhide
