[SOLVED] Arch efi partition error

Hiro8811@lemmy.world to Linux@lemmy.ml – 10 points –

I recently reinstalled arch but I have a problem with efi partition, user can acces it and the fstab is fucked up

Static information about the filesystems.

See fstab(5) for details.

I have tried modifying and regenerating fstab but it dosen't work. Also grub can't be accessed when I'm booted, nor does grub theme. How to I fix this?

Have you tried/installed nvme-cli and/or xnvme

I wonder if your issues come from buggy nvme modules

No that wasn't the problem. I should edit it as solved. What I did was delete the partitions and regenerate mkinicpio, delete all arguments and some grub configs. The efi partition still gets mounted but at least I need root privileges to modify and that's good enough

idk mybe your drive is fucked up so you should try a new one. also did you use fdisk or the graphical one ? and did you generate a new gpt/mbr tab ?

I solved it somewhat. There's only two entries in fstab now but for some reason the efi partition still gets automatically mounted and the grub theme dosen't work

1 are you using systemd-boot?

2 is your efi mounted as efi or boot?

3 depending on 2, manually unmount efi and see what you have on boot, maybe you have grub.cfg in 2 places.

@Hiro8811 @may_nya

  1. I think so, it ships with arch, right?
  2. I had it mounted in more places. First on /boot then in /grub and now it's in /efi.
  3. The grub.cfg config has always been in the same folder but I'll check it to make sure.

When I had an /efi mount just as arch said on wiki I didn't have problems. /boot stayed with root system, so it can be booted with efi or mbr.

If you have 2+ disks and one has mbr the other is gpt you can boot from either bootloader.

You should also try limine, less headaches than grub.

@Hiro8811

I have windows with broken efi partition on another disk but that's not important, or is it?

To turn os-prober on see /etc/default/grub -> false and install os-prober, then run grub-mkconfig -o ..

@Hiro8811

Dosen't work. At first the partition was dirty no I managed to run chxdisk(or whatever its called) and can mount it without hassle but it still dosen't appear in boot menu. I think there's something wrong with grub.cfg since the theme is not displaying but I don't know how to solve it

The theme itself is defined in grub.cfg, but it may be the case that it is stored in your root partition not in efi, so during bootloading the drive can't be read from.
So if you manually change the location of the theme directory and copy it inside efi it may work, and change the position of in grub.cfg

@Hiro8811

I was looking through commands history and I noticed something. If I'm mounting efi in /efi but I save grub-mkconfig -o to /boot/grub/grub.cfg during boot grub won't even notice the config file since root is not mounted. Should I save changes to /efi/grub/grub.cfg instead? Or /boot/grub/grub.cfg is the place it should be?

root must always be mounted if you have a system, either by booting or chroot. If you mount just efi from another system .
On my setup /efi/EFI/grub only has the grub efi binary no config, /boot and therefore /boot/grub is on /root partition

Now if you have the entire /boot in the /efi partition then it would be /efi/boot/grub/grub.cfg?

@Hiro8811

What I meant is that during boot efi partition gets mounted before root so it wouldn't be able to get config files from root partition. But that's not the problem, I tried regenerating grub. Most likely it's something wrong with the theme I applied. It keeps saying that it dosent found grub and that it should be mounted either in /efi or /boot but it is mounted. I'll try with grub-customizer.

Managed to get grub theme work so the grub is set up right. I guess I should stop being a help vampire. Anyway thanks for the help

reinstall arch without using archinstall maybe
