I just updated the system on my wife’s computer… And it doesn’t load anymore. The GRUB item is missing from the start screen. If you select any of the previous system snapshots (BTRFS), the system tries to start, but a line appears among the list of executed commands ```auto Failed to start Remount Root and Kernel File System. See 'systemctl status systemd-remount-fs.service' for details. ``` You need a computer to work and it’s just a disaster 😟 What could be the problem? ---

If you have the LTS kernel installed, you can boot those snapshots. If not, you can still restore them even if you can’t boot off them. That being said, restoring a snapshot probably won’t fix grub being missing. ---

Restore the entry would be possible from arch-chroot by reinstallation of the grub files after regenerating the grub.cfg. Question is what is the cause for the entry to disappear.

Question is what is the cause for the entry to disappear. I don’t know the reason… The computer was working all day - there were no problems. Then I updated the system and overloaded it. And the GRUB item on the home screen is gone… ---

sdb is your usb stick also looks like `/dev/nvme0n1p2` is the system and `/dev/nvme0n1p1` the efi partition (ESP boot partition) and as you said its BTRFS filesystem? so you need to mount the subvolumes. `sudo mount -o subvol=@ /dev/nvme0n1p2 /mnt` `sudo mount /dev/nvme0n1p1 /mnt/boot/efi` as of grub it will be on /boot/efi in your fstab… ![2024-04-29_00-29](https://forum.endeavouros.com/uploads/default/original/3X/8/a/8a1feaff85db356346259f9902fd864b1ef2571a.png) ---

Apparently I’m doing something wrong at all - it doesn’t work out. When I said that GRUB was missing, I meant this - the Endeavour record is missing ![IMG_20240429_014402](https://forum.endeavouros.com/uploads/default/original/3X/e/c/ecd9fcc8a997c7db2543e6f6cd89de5c6cb52ada.jpeg) ---
