[SOLVED] Failed to mount /boot/efi emergency mode

Devenda · 2014-07-30 14:16:19

My arch install worked perfectly until now.

Now I get this error when starting up:

Failed to mount /boot/efi

I probably got here by updating my system (pacman -Syu).

I tried following this solution in post #6 but couldn't get it to work.
Probably because those cp commands didn't work and I manually mounted my /boot from my arch install to some random folder (/var/empty) and copied the files there.

You have to know I'm rather new to arch/linux and the mounting didn't really make much sense...

What is the output of

mount /boot/efi

also

systemctl --failed

If the failed unit is boot-efi.mount then also the output of

systemctl -l status boot-efi.mount

This is what I got:

1.

 mount: unknown filesystem type 'vfat'

2.

boot-efi.mount loaded failed failed /boot/efi

3.

boot-efi.mount mount process exited, code=exited status=32
Failed to mount /boot/efi.
Unit boot-efi.mount entered failed state.

I also dual boot with windows 8, I hope to not lose the windows boot entry.

To check if the vfat module can be manually loaded

modprobe vfat

Did the pacman -Syu complete sucessfully?
This should not impact the Windows 8 entry.

modprobe vfat gives no errors

btw:

pacman -Q linux gives

 linux 3.15.7-1

but uname -a gives:

Linux ArchTinus 3.15.5-2-ARCH (...)

I hope this helps.

Your /boot wasn't mounted when you updated the kernel. Make sure it is and then -Syu before rebuilding your initrd.

Sorry but how do I do this?

Where do I mount /boot to?

I tried this but I can't get a network connection up (not in emergency mode and not while chrooted with life USB)

I'm rather new to this so maybe some kind of step by step explanation would help.

Thanks for your help!

Many thanks!

It worked although I also downgraded the kernel packages, because mkinitcpio -p linux gave an error. (didn't find the right file/directory)

How do I make sure that when I pacman -Syu the next time I don't get these problems again?

I'm on a UEFI system and read something about manually copying /boot files?

If your ESP is mounted at /boot, you don't need to do anything. See the wiki page on UEFI for details.

Please remember to mark your thread as [Solved] by editing your first post and prepending it to the title.

If the ESP is at /boot/efi and /boot is a separate partition as well then make sure both have have fstab entries and are mounted before the next upgrade
Edit:
This assumes the bootloader is using the kernel under /boot
