[SOLVED] Arch: Failed to start load kernel modules. Failed to mount /boot

FlintyGymnast55 · 09-11-2021, 03:10 PM

I am mostly new to using arch and i recently rebooted my pc and this error message showed up.

Failed to start load kernel modules
Failed to mount /boot

If anyone has any info on what the problem is or where i should continue looking, i would be eternally grateful.

After doing what?

Do you have a separate /boot partition? Did you have it mounted last update? /boot is where the kernel lives.

What are your partitions

Code:

fdisk -l
lsblk

What does your fstab look like?

Code:

cat /etc/fstab

Also

Code:

uname -a

I edited polybar, i3, lightdm configs, updated, and tried to get virtualbox to work before leaving my pc overnight and rebooting this morning.

I do have a separate /boot partition (/dev/sdb2) and i am pretty positive it was mounted last update.

Relevant partitions are:

/dev/sda2 : /home
/dev/sdb2 : /boot
/dev/sdb5 : root

Fstab is:

# /dev/sdb5
UUID=d07ea5cc-2ced-44fb-a7d3-968920fe4c55 / ext4 rw,relatime 0 1

# /dev/sda2
UUID=eaae17b1-d862-41d3-a22d-b2f3d7cdf98f /home ext4 rw,relatime 0 2

# /dev/sdb2
UUID=B272-A1A9 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 2

Uname -a is:

Linux archiso 5.13.13-arch1-1 #1 SMP PREEMPT Thu, 26 Aug 2021 19:14:36 +0000 x86_64 GNU/Linux

What are you using for a boot loader, and is this a duel boot system?

FlintyGymnast55 · 09-11-2021, 06:33 PM

I use grub and yes i dual boot windows 10

colorpurple21859 · 09-11-2021, 08:06 PM

My guess is the initramfs or /boot/grub/grub.cfg wasn't updated with a kernel update.

FlintyGymnast55 · 09-11-2021, 08:50 PM

I have gone through and made sure that initramfs and grub.cfg are both up to date

A little googling came across this https://bbs.archlinux.org/viewtopic.php?id=233935
what is the output of

Code:

stat /lib /lib64 /usr/lib

According to that you do not have /boot mounted.
You have /root as sdb2, but no /boot.

Please post the output of "sudo fdisk -l" so we can see what drive space you actually have and where. What you have posted only shows sda2, sdb2 & sdb5 so there are several partitions defined but not yet shown to us.

FlintyGymnast55 · 09-12-2021, 03:04 PM

Ive been at this issue for a while so i think the most recent time that i rebooted to my arch usb i accidentally mounted /dev/sdb2 to /root instead of /boot. sdb2 is most certainly supposed to be my /boot.

what is the contents of /boot without sdb2 mounted?
