[SOLVED] Boot fail at gpt-auto-root

So when i boot after my fresh install (not that fresh no because it's been some day i tried to fix it)
after the arch linux splash screen i have this error message

[ TIME ] Timed out waiting for device /dev/gpt-auto-root.
[DEPEND] Dependency failed for File system Check on /dev/gpt-auto-root.
[DEPEND] Dependency failed for Root Partition.
[DEPEND] Dependency failed for Initrd Root File System.
[DEPEND] Dependency failed for Mountpoints Configured in the Real Root.
[DEPEND] Dependency failed for Initrd Root Device.

You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup.

Cannot open acces to console, the root account is locked
See sulogin(8) man page for more details.

Press Enter to continue

If i press enter, i wait something like 2 minute and have the error message again start from "You are in emergency mode."

Actually the goal of the install is to have a lapdtop for school, so i have try to secure it the best i know.
For that i have choose to make 2 partion, one for /efi and one for the rest of arch (who is encrypt)

For the idea i follow the wiki ( https://wiki.archlinux.org/title/EFI_sy … unt_points ) so mount the esp to /efi

If using system encryption with the appropriate setup, it allows to leave only a few required files unencrypted while /boot remains protected:

Some setup i made

root@archiso ~ # lsblk                        
NAME                    MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINTS

└─nvme0n1p2             259:2    0 475.9G  0 part

    └─volgroup0-lv_home 254:2    0   300G  0 lvm   /mnt/home

In "/etc/fstab"

In /etc/mkinitcpio.d/linux-hardened.preset

# mkinitcpio preset file for the 'linux-hardened' package

#ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux-hardened"

PRESETS=('default' 'fallback')

#default_config="/etc/mkinitcpio.conf"
#default_image="/boot/initramfs-linux-hardened.img"
default_uki="/efi/EFI/Linux/arch-linux-hardened.efi"
default_options="--splash /usr/share/systemd/bootctl/splash-arch.bmp"

#fallback_config="/etc/mkinitcpio.conf"
#fallback_image="/boot/initramfs-linux-hardened-fallback.img"
fallback_uki="/efi/EFI/Linux/arch-linux-hardened-fallback.efi"
fallback_options="-S autodetect"

And after i generate initramfs
I setup some other thing with "systemd-firstboot --root /mnt --prompt"
And add a root psw and a user on the wheel

After that i reboot and here i have the error i give on the start of this message.

Re: [SOLVED] Boot fail at gpt-auto-root

the article you linked to also instructed to mount the ESP to /boot, which you did not do, as shown in /etc/fstab.

It is inside your root partition, which is encrypted. So the system has nothing to boot from.

Re: [SOLVED] Boot fail at gpt-auto-root

Solved

efibootmgr --unicode --disk /dev/nvme0n1 --part 1 --create --label "Archlinux Hardened" --loader /EFI/Linux/arch-linux-hardened.efi

create the file /etc/cmdline.d/00-root.conf with in it

rd.luks.name=2e242df4-36bc-4393-9664-ec0435283577=lv_root root=/dev/volgroup0/lv_root rw

regen the intraf with mkcpio

Reboot
