Grub says "Incorrect command" and "syntax error" when updating grub config

[artgamer]

the problem is in the title, i just was using grub customizer and it made this error all the time, updating grub manually via terminal didnt work too, what is the issue here? Grub cfg down below:

# GRUB boot loader configuration

GRUB_DEFAULT="0"
GRUB_TIMEOUT="5"
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"

# 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"

Thanks in advance!

@artgamer

i just was using grub customizer

I would strongly recommend against this. We have to help tons of people who broke their grub via grub-customizer.

That being said, in your case, you probably need to remove this exatra line from the top of your config:

  GNU nano 7.2  

[artgamer]

oh yeah, my bad

[artgamer]

Okay, but what now? How am i going to fix this?

[anon96028917]

why did you edit your post by deleting
GNU nano 7.2 ? so nobody sees the original issue

[dalto]

Can we see the full output of sudo grub-mkconfig

^^

[dalto]

So what is the issue at this point?

[artgamer]

i cant update the config

[anon96028917]

yeah in the file “grub” but NOT in the first posting in the forum…

[dalto]

@artgamer

i cant update the config

What does this mean?

Where can’t you you update the config? How are you trying? What error are you getting?

[anon11595408]

If you are on legacy (bios) grub, you might want to take a closer look to this forum entry:

Getting rid of grub customizer and restoring vanilla grub

Hi guys, been with EndeavourOS for a year and just loving it. Most stable distro I’ve ever had, and I’ve been distro-hopping for years. Now to my issue: a few months ago I installed “grub customizer” from the repo and it’s been working fine. Lately, however, arch decided to disable os-prober and this wasn’t a problem until I installed MX-Linux on my other drive. I ran grub customizer to add it automatically to grub but got error messages. Tried to add the line to grub.cfg about re-enabling os-p…

[dalto]

Would it be possible to get all the information at once?

What did you do to generate that output? What specific command did you run?

[artgamer]

sigh…

sudo grub-mkconfig -o /boot/grub/grub.cfg

[dalto]

But none of those errors in the output above when I asked you to run sudo grub-mkconfig

[artgamer]

yes, but the issue is that i cant edit anything without this error, which basically doesnt let me able to configure grub, which makes it a mess.

[dalto]

@artgamer

yes, but the issue is that i cant edit anything without this error,

What does this mean? Please stop only sharing part of the information.

Did you make a change between running sudo grub-mkconfig and sudo grub-mkconfig -o /boot/grub.cfg? If so, what change did you make and how did you make it?
