Copy your /boot/grub/grug.cfg menuentry line to /etc/default/grub GRUB_DEFAULT=

quartz knoll Dec 6, 2025, 4:06 AM

#

quartz knoll Dec 6, 2025, 8:07 AM

#

do you mean line 131?

#

for copying

low agate Dec 6, 2025, 11:18 AM

#

quartz knoll do you mean line 131?

edit /etc/default/grub; GRUB_DEFAULT='Arch Linux'

#

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

quartz knoll Dec 6, 2025, 2:09 PM

#

my default arch linux entry in grub still tries to boot to linux-lts

#

even aftert those changes

eternal hedge Dec 6, 2025, 7:57 PM

#

quartz knoll

on line 144 delete the "-lts" after the vmlinuz-linux

#

on line 146 do the same thing after initramfs-linux

#

make sure you have vmlinuz-linux (without the -lts) in your /boot folder otherwise it won't boot. same with initramfs

quartz knoll Dec 6, 2025, 10:40 PM

#

i made sure i had all the files ik have all of them with and without -lts

#

and i edited those lines and got rid of the -lts properly

#

but the default boot entry still tries to boot into linux-lts

eternal hedge Dec 6, 2025, 11:14 PM

#

you should be able to edit the entries from grub itself. when it comes up, instead of pressing enter to select it, press "e" to edit. I think it's "e" at least

#

look at the entry and see if it's correct, otherwise you can change those lines I mentioned earlier and then boot it

quartz knoll Dec 7, 2025, 11:53 AM

#

So I edited the lines

#

In grub itself

#

But it didn't save

#

When I rebooted

#

And tried it again

#

It didn't work

#

For some reason

#

It runs a command line

#

#

I changed it

#

Got rid of the -lts

#

It boots normally

#

Then the options at the bottom

#

Are tab lists completion

#

Press Ctrl x or F10 to boot, Ctrl c or F2 for a command-line (opens terminal) or ESC to discard edits and return to grub menu

#

If I click Ctrl x or f10 to boot after making changes

#

It boots

#

But then I rebooted

#

And it doesn't save the changes I made

low agate Dec 7, 2025, 1:31 PM

#

/etc/grub.d/40_custom menuentry "Arch Linux" { ... }

low agate Dec 7, 2025, 1:33 PM

#

quartz knoll And it doesn't save the changes I made

Create custom menuentry and regnerate grub.cfg;

quartz knoll Dec 7, 2025, 1:36 PM

#

where do i pu t it?

#

wait nvm

#

i didnt read 😭

#

but what goes in the { . . .}

#

and do i just write menuentry "Arch Linux" ?

low agate Dec 7, 2025, 1:40 PM

#

Do you have /etc/grub.d/10_Linux ? Change it instead.

quartz knoll Dec 7, 2025, 1:41 PM

#

?

#

where would i put it in this?

low agate Dec 7, 2025, 1:41 PM

#

what is the content?

quartz knoll Dec 7, 2025, 1:42 PM

#

#

a lot

low agate Dec 7, 2025, 1:43 PM

#

no, keep it as it is.

quartz knoll Dec 7, 2025, 1:44 PM

#

alright

#

so do i change 40_custom?

low agate Dec 7, 2025, 1:46 PM

#

to make your file has higher priority, you need a file with lower number then 10_liunx. t.ex 09_custom.

quartz knoll Dec 7, 2025, 1:47 PM

#

so i can just rename 40_custom

#

or can i?

#

to 09_custom

low agate Dec 7, 2025, 1:48 PM

#

yes

quartz knoll Dec 7, 2025, 1:48 PM

#

how do i do that exactly

#

i need to do it in terminal

#

since it wont let me through dolphin

low agate Dec 7, 2025, 1:49 PM

#

sudo mv 40_custom 10_custom

#

sudo chmod a=rx 10_custom

quartz knoll Dec 7, 2025, 1:51 PM

#

i am the super user but its still not working

#

i am in the directory as well

low agate Dec 7, 2025, 1:54 PM

#

you can create 10_custom file in your home directory first and move to /etc/grub.d/ later on.

quartz knoll Dec 7, 2025, 1:54 PM

#

wouldnt it need to be an 09_custom file so it has highier priority than 10_linux

low agate Dec 7, 2025, 1:54 PM

#

yes

quartz knoll Dec 7, 2025, 1:55 PM

#

alright i made it

#

its a txt file atm

#

and its fully empty

low agate Dec 7, 2025, 1:56 PM

#

cat <<EOF
menuentry "Arch Linux" {
...
}
EOF```

quartz knoll Dec 7, 2025, 1:56 PM

#

? like this

#

wouldnt i need the comment lines from this

quartz knoll Dec 7, 2025, 1:56 PM

#

quartz knoll where do i pu t it?

.

#

and the exec line

#

especially the exec line

low agate Dec 7, 2025, 1:57 PM

#

no exec line needed. you need to replace ... with your content.

quartz knoll Dec 7, 2025, 1:58 PM

#

like i did?

#

oh

#

wait

#

wym replace ... with my content

low agate Dec 7, 2025, 2:03 PM

#

quartz knoll wym replace ... with my content

quartz knoll Dec 7, 2025, 2:03 PM

#

wait a min

#

this part right here

#

is what shows up when i boot

#

its also the few lines i changed when i edited grub

#

within grub its selfd

low agate Dec 7, 2025, 2:04 PM

#

This is the content you need to replace ...

quartz knoll Dec 7, 2025, 2:05 PM

#

wouldnt i need to get rid of that -lts tho in the bottom?

low agate Dec 7, 2025, 2:05 PM

#

yes

quartz knoll Dec 7, 2025, 2:06 PM

#

what file was that from again?

#

grub.cfg?

low agate Dec 7, 2025, 2:06 PM

#

You need all content inside 09_custom

quartz knoll Dec 7, 2025, 2:07 PM

#

from menu entry to initramfs-linux-lts.img

#

but just remove the -lts ofc

#

would i copy this one?

#

#

or this one

#

also couldnt i just get rid of the menu entry for -lts since it doesnt work to begin with

#

this is the grub.cfg

#

just checking if i can do other options other than 09_custom righ tnow

#

idm doing the custom obviously its just any idea could work

low agate Dec 7, 2025, 2:18 PM

#

please show 09_custom

quartz knoll Dec 7, 2025, 2:20 PM

#

low agate Dec 7, 2025, 2:21 PM

#

yes

quartz knoll Dec 7, 2025, 2:22 PM

#

so now what

low agate Dec 7, 2025, 2:23 PM

#

sudo cp 09_custom /etc/grub.d/

#

sudo chmod a=rx /etc/grub.d/09_custom

quartz knoll Dec 7, 2025, 2:25 PM

#

oh yeah do i get rid of the txt?

#

so it turns into an empty file

#

i would have to turn it into a shell script

#

like all the other ones

low agate Dec 7, 2025, 2:26 PM

#

quartz knoll oh yeah do i get rid of the txt?

What txt?

quartz knoll Dec 7, 2025, 2:26 PM

#

i did it wrong one sec

#

i made the 09_custom a text file

#

just wait

#

thats the file i made its in my home atm

#

wait

#

i think i did it

#

#

there we go

#

dont mind the .txt i moved it there by mistake

#

i shouldve just made an empty file and didnt realize it was a txt 😭

low agate Dec 7, 2025, 2:30 PM

#

sudo rm -f /etc/grub.d/09_custom.txt

quartz knoll Dec 7, 2025, 2:31 PM

#

alr done

#

low agate Dec 7, 2025, 2:31 PM

#

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

quartz knoll Dec 7, 2025, 2:32 PM

#

alright ima reboot and see if it worked

#

if not ill report back

#

It still runs Linux-lts

low agate Dec 7, 2025, 2:34 PM

#

You should remove 40_custom and 41_custom.

quartz knoll Dec 7, 2025, 2:39 PM

#

alright i removed them

quartz knoll Dec 7, 2025, 2:40 PM

#

low agate ```sudo grub-mkconfig -o /boot/grub/grub.cfg```

do i run this again?

low agate Dec 7, 2025, 2:42 PM

#

quartz knoll do i run this again?

yes

quartz knoll Dec 7, 2025, 2:45 PM

#

Still boots -lts

low agate Dec 7, 2025, 3:00 PM

#

quartz knoll Dec 7, 2025, 3:02 PM

#

#

#

low agate Dec 7, 2025, 3:11 PM

#

/etc/default/grub GRUB_DISABLE_SUBMENU=y

quartz knoll Dec 7, 2025, 3:13 PM

#

#

low agate Dec 7, 2025, 3:14 PM

#

quartz knoll Dec 7, 2025, 3:17 PM

#

quartz knoll Dec 7, 2025, 3:17 PM

#

low agate ```sudo grub-mkconfig -o /boot/grub/grub.cfg```

?

low agate Dec 7, 2025, 3:19 PM

#

You don't have to ask this every time. this is standard, every time you change anything related to grub, you need to do this. :D

quartz knoll Dec 7, 2025, 3:19 PM

#

just making sure 😭

low agate Dec 7, 2025, 3:21 PM

#

before reboot, show /etc/grub/grub.cfg

quartz knoll Dec 7, 2025, 3:25 PM

#

#

also

#

i didnt read the before reboot message

#

but it did do smth

#

it got rid of the original Arch linux menuentry

#

now it has both arch linux -lts and regular arch linux linux

#

bascially what ever i would see in advanced options is what is there

#

and the default arch linux boot entry is gone

#

heres the rest of the file btw

low agate Dec 7, 2025, 3:27 PM

#

show /etc/default/grub

quartz knoll Dec 7, 2025, 3:28 PM

#

low agate Dec 7, 2025, 3:31 PM

#

are you able to boot? which entry?

quartz knoll Dec 7, 2025, 3:31 PM

#

ill show you what shows up now

#

the default arch linux entry is gone

#

i only see -lts and arch linux linux

low agate Dec 7, 2025, 3:32 PM

#

quartz knoll the default arch linux entry is gone

No, the submenu entry is gone.

quartz knoll Dec 7, 2025, 3:32 PM

#

#

The arch Linux entry is gone and everything that was in the sub menu is there

#

Linux Linux -lts doesn't work only Linux Linux works

low agate Dec 7, 2025, 3:34 PM

#

quartz knoll Linux Linux -lts doesn't work only Linux Linux works

Correct!

quartz knoll Dec 7, 2025, 3:35 PM

#

Is there a way for me to also get rid of the -lts entry?

#

So it's only the working entry and windows

#

And uefi

low agate Dec 7, 2025, 3:38 PM

#

quartz knoll Is there a way for me to also get rid of the -lts entry?

sudo chmod -x /etc/grub.d/10_linux

#

/etc/default/grub GRUB_DEFAULT=0

#

I need go now, do your best!

quartz knoll Dec 7, 2025, 3:48 PM

#

Yea no worries thanks I'll give any updates if it does or doesn't work

#

Okay so the Linux entry is gone .

#

Like nothing

#

Once I changed it to grub_defsult =0

low agate Dec 7, 2025, 10:27 PM

#

quartz knoll Once I changed it to grub_defsult =0

What entries do you have now?

quartz knoll Dec 8, 2025, 1:09 AM

#

Windows, uefi system

#

Thats it

#

No arch Linux what so ever

low agate Dec 8, 2025, 1:21 AM

#

quartz knoll Windows, uefi system

What are inside /boot/grub/grub.cfg ?

quartz knoll Dec 8, 2025, 1:21 AM

#

I can't check

#

I can't see my Linux files

#

Since I can't boot to Linux without the grub entry

low agate Dec 8, 2025, 1:22 AM

#

quartz knoll Since I can't boot to Linux without the grub entry

you can boot with archlinux.iso from USB.

quartz knoll Dec 8, 2025, 1:23 AM

Supposedly

low agate Dec 8, 2025, 1:30 AM

which one is your archlinux partition?

quartz knoll Dec 8, 2025, 1:31 AM

#

Sda 7 is my arch Linux swap sda 5 is my EFI and sda 6 is my Linux filesystem

#

I would assume it would be in sda 6

mount /dev/sda6 /mnt

#

#

quartz knoll Dec 8, 2025, 1:37 AM

#

But I can still boot into grub so idk

#

Okay so I just did ls boot

#

And it's completely empty

#

Nothing showed up as an output to ls boot

low agate Dec 8, 2025, 1:46 AM

#

quartz knoll Nothing showed up as an output to ls boot

your boot partition is located at sda5.

#

do this instead.

mount /dev/sda6 /mnt
