BIOS update wiped my bootloader

I’m trying to reinstall my bootloader but I’m having an issue (I’m using UEFI).

What I’ve tried so far:

  1. Using the EndeavourOS live-usb, I mounted the root partition, /dev, /sys, /proc, and efi partition

  2. Chrooted into root partition

  3. entered “bootctl install”

My only problem is the last result of the command says “Failed to write ‘LoaderSystemToken’ EFI variable: No such file or directory”.

Perhaps the output of the following commands might give forum members experienced with systemd-boot some clues:

sudo parted -l

efibootmgr -v

and the content of /etc/fstab from your installed system.

Also using arch-chroot you wouldn’t need to mount /dev, /sys, etc.
Depending on your boot mode, you just need to mount your root partition and ESP in case of UEFI.

I fixed it thanks, I just used arch-chroot instead of chroot and somehow the issue was resolved. Big thanks.

wait nevermind, I rebooted and I just see “Reboot to Firmware Interface” even though bootctl install went smoothly

Have a look here and check if your loaders are correctly configured:

I don’t fully understand what I’m doing but here’s what I’ve tried so far:

  1. chrooted to root mountpoint
  2. created an endeavouros.conf at /efi/loader/entries/

What I wrote inside the endeavouros conf file:

title EndeavourOS Linux x86_64
efi /vmlinuz-linux
options root=dev nvidia-drm.modeset=1 ibt=off
  1. entered “sudo bootctl update”
  2. exit chroot and unmounted the partitions
  3. rebooted

After rebooting, I still run into the “Reboot to Firmware Interface” issue in systemd-boot

I would try something like

title   EndeavourOS Linux x86_64
linux   /vmlinuz-linux
initrd  /intel-ucode.img ## or amd-ucode.img in case of AMD
initrd  /initramfs-linux.img
options root=UUID=xxxx rw nvidia-drm.modeset=1 ibt=off ## replace xxxx with the UUID of the root partition

If you are using EOSes systemd-boot setup you shouldn’t be creating manual entries. That will just leave you with a mess.

It should be sufficient to arch-chroot in and run sudo reinstall-kernels
