Kernel panic - not syncing No working init found.

Hello. Help me please and sorry for my bad english.
I have Kernel panic after force update pacman -Syu (Yes. I am stupid). I reboot my PC and have KP (No working init found).
In the internet I found that need to try init=/bin/bash. After it I have error "Kernel panic: Request init /bin/bash failed (error -2)".
On Arch-wiki I found theme Kernel Panic and read it. I boot from USB, use mount, chroot, find 'linux*', pacman -U.
Now KP (with init=/bin/bash) is:
Failed to execute /init (error -2)
Failed to execute /bin/bash (error -2). Attempting defaults... ,
Kernel panic - not syncing No working init found. Try passing init= option to kernel.

Re: Kernel panic - not syncing No working init found.

You'll need to provide more information about your setup: partition table, boot loader/manager, configuration for that tool, what was in the update (look in pacman's log), etc...

Re: Kernel panic - not syncing No working init found.

Partition table:

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048   419432447   209715200   83  Linux
/dev/sda2       419432448   427821055     4194304   82  Linux swap / Solaris
/dev/sda3       427821056  1953525167   762852056   83  Linux

Bootloader is GRUB2. What config are needed?

Re: Kernel panic - not syncing No working init found.

Better to chroot into partition and try to remake initramfs

# mkinitcpio -p linux

do it good first, it will be faster than do it twice the saint wink

I take it you ran the `lsblk -f` command from an Ubuntu live system?

That command in Debian/Ubuntu will only show what I wanted to see with superuser permissions...

We need to see the UUIDs -- post the output of:

I wanted update some software. And I decided update all software.

Did you have to use `pacman -Syu --force`?

If so, what were the error messages given by pacman that lead you to use this flag?

OK, sorry for being a bit rude -- I was confused.

You should probably chroot into your system and re-install the kernel image & GRUB and re-configure GRUB.

EDIT: How long has it been since you last updated your system?

Re: Kernel panic - not syncing No working init found.

I would also use an archlinux live-cd, it provides arch-chroot giving you a better chance of reviving your install

Re: Kernel panic - not syncing No working init found.

No problem.
I already use
"pacman -U /var/cache/pacman/pkg/linux-3.19.3-3-x86_64.pkg.tar.xz"
and
"mkinitcpio -p linux"
both in arch live-cd. And nothing has changed.

Now I use "pacman -S grub"

How I must re-configure GRUB?

What do you mean by "updated system". I new arch user (about a month)

Re: Kernel panic - not syncing No working init found.

^ You have not mounted /proc, /sys & /dev
https://wiki.archlinux.org/index.php/Change_root

As @Spider.007 says, you should use the Arch live ISO and `arch-chroot` -- just as you did (?) when installing Arch.

Re: Kernel panic - not syncing No working init found.

I use Ubuntu liveCD, because I can't copy output on forum without reboot. OK, I will try again reconfigure in arch.
Of course I used the chroot when install arch smile

Did you mount your partition(s) and use `arch-chroot` before you did this?

Have you re-installed GRUB (from within the chroot)?

When I install bootloader I get this message

Some changes. Now I get grub error.

What  specifically did you command?  It looks like you specified a volume, not a drive.
