Use your live usb to chroot: ```auto sudo mount /dev/nvme0n1p2 /mnt sudo mount /dev/nvme0n1p1 /mnt/boot/efi sudo arch-chroot /mnt ``` Inside chroot: `pacman -Syu` `grub-install --efi-directory=/boot/efi bootloader-id=endeavouros` `grub-mkconfig -o /boot/grub/grub.cfg` Reboot. ---

I have tried something similar. I will give this another shot after work today. ---

What I am curious about the way grub was updated , I thought you should always run ```auto sudo grub-install sudo grub-mkconfig -o /boot/grub/grub.cfg ``` Now I saw that only the last command was used by the OP , could that have messed up the grub bootloader ? ---

As I understand it, unless first install or a new version of grub is published, you only need the 2nd. However, it doesn’t hurt to over write the bootloader unnecessarily. ---

This may have to do or not with OP’s issue but at any rates the output of the` efibootmgr` shows that they lack the _default_ bootpath to bootloader’s efi binary `\EFI\endeavouros\grubx64.efi` They only have the _fallback_ bootpath (Boot0002) `\EFI\BOOT\BOOTX64.EFI0000424f` So as already mentioned, this may not be the issue but creating the default bootpath, trying to boot from that and if the issue still persists, this will help to eliminate the Grub’s bootloader as a potential issue. ---

That is interesting if I would have adviced refind as bootloader no grub was needed right ? [Previous page](https://forum.endeavouros.com/t/cannot-update-linux-or-linux-headers-causes-boot-failure/70532.md?page=1)
