After change something on the grub.cfg file the o.s. cannot boot

i dont know what is the cause of this problem i just change timeout=0 in the grub.cfg file and update grub but when i choice on the menu “manjaro” it appear just the prompt ,iknow that can log with alt+ctrl+F2 but all kind of update pacman cant restore the system as first… someone can help me?

Have to be changed here: /etc/default/grub and then update-grub.

/boot/grub/grub.cfg is generated.

hi ,maybe i had changed /etc/default/grub right, but the grub work and after i choose the system manjaro i can see the 3 tiny central point of the system loading but after it not show the desktop ,but only the prompt in black screen and fan run fast,
now i have switched on my pc and am on live cd and i can run all comman you ask to resolve this issue… just ask thans

Then you need to use the Manjaro USB stick and chroot into the system.

i have tried manjaro-chroot from live cd ,i think it s right…?
i also tried pamac snap ecc... mkinitcpio. ecc...
but the issue cant solve
sorry but i am a newbie
i don t want re-install the system because i made it just 2 day ago…
only do not want wait the grub countdown…:sob:

so revert the changes you made?
and the issue you describe doesnt look like its caused by changing the timeout… since you can enter into TTY…
so first, boot into manjaro live usb, connect to internet, chroot:
manjaro-chroot -a
and rerun update:
pacman-mirrors -f 5 && pacman -Syyu
are there any errors from this? if yes post them here

hi,ok

[manjaro /]# 

and everything was working before you edited the grub?
reinstall your kernel and install also the 515:
pacman -S linux61 linux515
if there are errors post them here;

open this:
nano /etc/default/grub
and edit these to look like this:

GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=menu

save it with ctrl+x; update grub:
update-grub
reboot and try booting with the 515 kernel

yes of course! it s very fast before… the system have done installed that kernel but in my grub file i have GRUB_TIMEOUT_STYLE=hidden an i overwrite GRUB_TIMEOUT_STYLE=menu (i hope its right)
and this is the result of update-grub

did you tried with the 5.15 kernel?
post again logs:
journalctl -b-1 -p4 --no-pager

i dont know that i need to choose let me try again…

ok my friend,now it work :grinning:,i choose the 5.15 kernel inside the advanced grub option,maybe something damaged in the previous kernel…

[hello@computer ~]$ 

so you booted normally with the 5.15 kernel?

and also i noticed you are having windows… fast startup needs to be disabled in windows, otherwise it can cause issues

ok soon i go resolve this thing ,now ther is reason to return to the last kernel 6.xx or i can wor normaly in this same?

yes use the 5.15 … and try reinstalling the 61, remove it first:
sudo mhwd-kernel -r linux61
install it again:
sudo mhwd-kernel -i linux61
reboot and try booting again with it…
but first boot into windows and disable the fast startup

ok… i notice you later… but what could it have cause this damage on the kernel ? fast startup ?

really dont know… and the fast startup is not likely the cause, but it should be disabled anyway, so do it… maybe the reinstall mentioned in the command above will resolve it…
