GRUB doesn't show linux mint after installing EndeavourOS

So, in my grub.cfg file the last line “GRUB_DISABLE_OS_PROBER=false” is already present, but when I go to update the grub using the command “sudo grub-mkconfig -o /boot/grub/grub.cfg” I get this warning: "Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.

My grub file:

GNU nano 7.2 /etc/default/grub

GRUB boot loader configuration

GRUB_DEFAULT=‘0’
GRUB_TIMEOUT=‘35’
GRUB_DISTRIBUTOR=‘EndeavourOS’
GRUB_CMDLINE_LINUX_DEFAULT=‘nowatchdog nvme_load=YES loglevel=3’
GRUB_CMDLINE_LINUX=“”

Preload both GPT and MBR modules so that they are not missed

GRUB_PRELOAD_MODULES=“part_gpt part_msdos”

Uncomment to enable booting from LUKS encrypted devices

#GRUB_ENABLE_CRYPTODISK=y

Set to ‘countdown’ or ‘hidden’ to change timeout behavior,

press ESC key to display menu.

GRUB_TIMEOUT_STYLE=menu

Uncomment to use basic console

GRUB_TERMINAL_INPUT=console

Uncomment to disable graphical terminal

#GRUB_TERMINAL_OUTPUT=console

The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command `videoinfo’

GRUB_GFXMODE=auto

Uncomment to allow the kernel use the same resolution used by grub

GRUB_GFXPAYLOAD_LINUX=keep

Uncomment if you want GRUB to pass to the Linux kernel the old parameter

format “root=/dev/xxx” instead of “root=/dev/disk/by-uuid/xxx”

#GRUB_DISABLE_LINUX_UUID=true

Uncomment to disable generation of recovery mode menu entries

GRUB_DISABLE_RECOVERY=‘true’

Uncomment and set to the desired menu colors. Used by normal and wallpaper

modes only. Entries specified as foreground/background.

#GRUB_COLOR_NORMAL=“light-blue/black”
#GRUB_COLOR_HIGHLIGHT=“light-cyan/blue”

Uncomment one of them for the gfx desired, a image background or a gfxtheme

GRUB_BACKGROUND=‘/usr/share/endeavouros/splash.png’
#GRUB_THEME=“/path/to/gfxtheme”

Uncomment to get a beep at GRUB start

#GRUB_INIT_TUNE=“480 440 1”

Uncomment to make GRUB remember the last selection. This requires

setting ‘GRUB_DEFAULT=saved’ above.

#GRUB_SAVEDEFAULT=true

Uncomment to disable submenus in boot menu

GRUB_DISABLE_SUBMENU=‘false’

Probing for other operating systems is disabled for security reasons. Read

documentation on GRUB_DISABLE_OS_PROBER, if still want to enable this

functionality install os-prober and uncomment to detect and include other

operating systems.

#GRUB_DISABLE_OS_PROBER=false

Here is what I get in full:

How can I do to resolve it? Obviously I’m new to the Linux environment, so I prefer to ask before doing it myself.

For better readability, please format the pasted text. You can do so by highlighting the pasted text and pressing Ctrl-E.

Uncomment this line

#GRUB_DISABLE_OS_PROBER=false

in /etc/default/grub and regenerate your grub.cfg.

Sorry for the noob, but what does uncomment the line mean? Should I delete it? Should I remove the “false” and that’s it?

Remove the # at the beginning of the line.

Thanks!
