Grub don't want to show up

(I am not english speeker, so if you don’t understand something just ask for rewrite)

Me a idiot accidentally restarted the pc during an update, and when as trying to boot manjaro grub can’t find the kernel, picked my live-usb and go trying fix the problem, as espected of a noob i made the situation worse, now the grub is missing.

What i remember doing:
• Majaro-chroot and pacman -Syu
ー result: nothing
• update grub
ー result: nothing
• reinstall grub
ー result: no grub any more

System Info:
•Dual boot:

And a strange thing is that i have 3 efi: win10, manjaro go back to bios and the other to grub rescue.

so first chroot:
manjaro-chroot -a
rerun update:
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
if no errors, post output from:
mhwd-kernel -li

Just manjaro should suffice.

no errors

[manjaro /]# mhwd-kernel -li
Currently running: 5.15.60-1-MANJARO (linux515)
The following kernels are installed in your system:
   * linux515

so reinstall the 515:
pacman -S linux515
reinstall grub:

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck 

update it:
mkinitcpio -P && update-grub
if no errors, exit chroot:
reboot and see if it helped


do this:
sudo nano /etc/default/grub
and change this line to look like this:
GRUB_TIMEOUT_STYLE=menu - its third from top;
save the file with: ctrl+x and run this:
sudo update-grub
reboot and check
