Grub-mkconfig fails

Thomqa · 2015-08-28 10:14:29

Hi everybody,

I'm trying to install Arch Linux on my laptop (dualboot with windows 10) but I have some trouble installing the bootloader GRUB. When I ran the mkconfig command I got some strange output.

 # grub-mkconfig -o /boot/grub/grub.cfg

Generating grub configuration file ...
[ 3264.369373] FAT-fs (sda3): bogus number of reserved sectors

[ 3264.378617] ntfs: (device sda3): ntf_fille_super(): Not an NTFS volume.

I used to have a error like this:

/run/lvm/lvmetad.socket: connect failed: No such file or directory
  WARNING: Failed to connect to lvmetad: No such file or directory. Falling back to internal scanning.

But i 'fixed' that with the suggestion given here: http://unix.stackexchange.com/questions … wer-152277

My partitions look like this:

When trying to boot into Arch Linux I get the GRUB bash interface.

Is there somebody who knows how to fix this problem and is willing to help me? It would be much appreciated!

Code may contain typos, had to retype it....

Which command did you use to install GRUB?

We need to know how your folders and partitions are mounted.

Load the Arch live ISO, mount all of your partitions, use `arch-chroot` then post the output of:

lsblk

You can use a pastebin client to generate a URL that can be posted here.

First of all, thank you very much for the pastebin tip!

My drive layout is as follows:

└─arch_airootfs 254:0    0    32G  0 dm   /etc/resolv.conf

I used the command as given in the beginners guide. First I downloaded the extra packages:

# pacman -S dosfstools efibootmgr

And then installed grub:

# grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=arch_grub --recheck

Which gives the following output:

Installing for x86_64-efi platform.
Installation finished. No error reported.

And then (as said before) I used the config command:

# grub-mkconfig -o /boot/grub/grub.cfg

Output:

If you just run `grub-mkconfig` does it spit the configuration file to stdout?

That file is empty, there are no menu entries.

Have you installed os-prober?

Is Windows running in UEFI mode?

You could try creating your own grub.cfg
http://www.gnu.org/software/grub/manual … figuration

This can be far simpler than you might think -- here is mine:

set default=0
set timeout=5

insmod part_gpt
insmod ext2

menuentry "Arch" {
insmod fat
set root=(hd0,1)
	linux /vmlinuz-linux root=/dev/sda2 rw quiet ipv6.disable=1
	initrd /intel-ucode.img /initramfs-linux.img
}

menuentry "Arch LTS" {
insmod fat
set root=(hd0,1)
	linux /vmlinuz-linux-lts root=/dev/sda2 rw quiet ipv6.disable=1
	initrd /intel-ucode.img /initramfs-linux-lts.img
}

menuentry "Debian Sid" {
set root=(hd0,4)
	linux /vmlinuz root=UUID=191c641f-66ed-47fc-9adb-df2b189ed367 rw quiet ipv6.disable=1
	initrd /initrd.img
}

menuentry "Linux From Scratch 7.7" {
set root=(hd0,6)
        linux /boot/vmlinuz-4.0.1-lfs-7.7-systemd root=/dev/sda6 ro quiet ipv6.disable=1
}

Thomqa · 2015-08-31 20:11:36

Yes, windows runs in UEFI mode and os-prober is installed.

Okay, that clears things up.

I will try that. I still wonder why mkconfig doesn't work as expected.

Thomqa · 2015-08-31 20:51:48

Okay, I might have forgotten to mount the EFI partition to /mnt/boot before installing arch. That could be the cause of these problem right? After I was able to properly configure a menuentry it failed to boot because it couldn't find /vmlinuz-linux.....

Yes, that would do it.

You could load up the live Arch ISO, mount *all* of your partitions, use `arch-chroot` and then re-install your kernel image and bootloader and re-configure GRUB.

Thomqa · 2015-08-31 21:05:20

Okay, I see. In the installation guide they first install the base package with 'pacstrap' before 'arch-chroot'. How would I reinstall my kernel image after changing root? Does 'pacstrap' still work?

Hey guys, I'm having a very similar issue with the exact same error. I have a RAID0 setup on two SSDs that is IDed as /dev/md126. I have Windows 10 installed on that device. So my EFI partition is located on /dev/md126p2. I am trying to install Arch on a separate HDD (/dev/sda) which has three partitions:
1. /dev/sda1: MBR
2. /dev/sda2: Linux Swap
3. /dev/sda3: Linux File System

I followed all the instructions from the Arch Beginner's Guide, the only notable part is that I mounted /mnt/boot from /dev/md126p2, since that is my EFI partition. Note that the EFI partition is on a different device than the Arch Linux installation. Running grub-mkconfig, I got this:

>[ 3441.362966] FAT-fs (md126p3): bogus number of reserved sectors
>[ 3441.362966] squashfs: SQUASHFS error: Can't find a SQUASHFS superblock on md126p3

I can see how the problem arose, but I'm not sure how to fix it. Any kind of help would be greatly appreciated.

Try booting up your newly-installed Arch system and re-run `grub-mkconfig` again from there.

EDIT: To generate a working grub.cfg you may have to (temporarily) un-install os-prober so that `grub-mkconfig` can complete without error from the installation environment.
