[SOLVED]Grub doesn't detect Arch, even though I configure it from Arch
Hi, I am trying to add other os boot options to grub. What I did (all maybe relevant information):
Edit fstab (this was not required, but this is just something I wanted to do): (fstab has been backed up)
# Static information about the filesystems.
# See fstab(5) for details.
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/nvme0n1p6
UUID=c2cb89b8-c6a7-44f2-ba26-98be335a5a10 / ext4 rw,relatime 0 1
# /dev/nvme0n1p3
UUID=71D5-4ADD /efi vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 2
UUID=93f408be-c02a-4c67-a0b4-14be490f1e6f /ubuntu ext4 rw,relatime 0 3/ubuntu is just a mount of my ubuntu partition so I can access my files, this already existed. My change was to change /boot into /efi
I rebooted at this point to see if this would work fine, it did. I saw no errors when booting.
Then I ran this command:
grub-install --target=x86_64-efi --efi-directory=/efi --bootloader-id=Universal Bootthis gave no errors
Then I ran this: (I backed up the old config)
grub-mkconfig -o /boot/grub/grub.cfgit outputted this:
Generating grub configuration file ...
Warning: os-prober will be executed to detect other bootable partitions.
Its output will be used to detect bootable binaries on them and create new boot entries.
Found Windows Boot Manager on /dev/nvme0n1p1@/efi/Microsoft/Boot/bootmgfw.efi
Found Ubuntu 22.04.3 LTS (22.04) on /dev/nvme0n1p5
Adding boot menu entry for UEFI Firmware Settings ...
doneHere lies the problem, when I tried this previously, I just rebooted at this point and only then figured out that I couldn't boot back into arch (thank god for the backup). I know at this point why I wasn't able to, this is the config it generated:

Re: [SOLVED]Grub doesn't detect Arch, even though I configure it from Arch
When "changing /boot to /efi" did you copy over initramfs and vmlinuz-linux-zen over to /boot as well/reinstalled the linux package so that the relevant images get regenerated?

Re: [SOLVED]Grub doesn't detect Arch, even though I configure it from Arch
this is what /efi contains:
❯ la
total 116M
drwxr-xr-x 5 root root 4.0K Oct 11 00:05 EFI
-rwxr-xr-x 1 root root 36M Oct 10 23:06 initramfs-linux-fallback.img

-rwxr-xr-x 1 root root 14M Oct 9 16:18 vmlinuz-linux-zenDo I need to move the images back to /boot?
I tried doing
sudo mkinitcpio -p linux-zenand it complained saying this:
==> Building image from preset: /etc/mkinitcpio.d/linux-zen.preset: 'default'
==> Using default configuration file: '/etc/mkinitcpio.conf'

==> ERROR: specified kernel image does not exist: '/boot/vmlinuz-linux-zen'I would normally just copy things over but I'm trying to not break my system
EDIT: /boot only contains a grub dir with all the grub files in there

Re: [SOLVED]Grub doesn't detect Arch, even though I configure it from Arch
Yes copy all of these over to /boot. I'd surmise that's your reason for switching ESP locations, is it not?
