[SOLVED] Boot problem. ERROR: device 'UUID=' not found. Skipping fsck.

After yesterday updating and reboot. During boot i met next load issue:
https://pp.userapi.com/c824602/v8246022 … opceAc.jpg

console unavailable.

i go to liveCD and launch:

 mint@mint ~ $ lsblk -f

i mount all and reconfigure grub.cfg through chroot, grub.cfg:

Re: [SOLVED] Boot problem. ERROR: device 'UUID=' not found. Skipping fsck.

Please use code tags, no quote tags.
There's no "88a" in the grub.cfg (or your lsblk)
If you've a separate boot partition, the most likely reason is that you forgot to mount that during a kernel update.
Another pot. cause is that you've this UUID in your fstab and no "noauto" option to it. If the device isn't there, you're being dropped to an emergency shel.

Re: [SOLVED] Boot problem. ERROR: device 'UUID=' not found. Skipping fsck.

Please, code block instead of quote blocks.

Anyway, it looks you're booting an old kernel with the wrong initramfs, or there was a problem when generating the initramfs. Boot an install disk, mount *all* necessary partitions, chroot, and reinstall the linux package.

sry, my bad, change all to code tags.

i don't have separate boot partition (all locate on /sda2)
i don't get why during boot system don't see sda2 (error UUID it's sda2 - that's my "/").

Excuse me, "install disk" - d u mean LiveCD ?
and reinstall linux package ? do u mean try like this: pacman -Sf linux ?

What, exactly, do you think the "f" in pacman -Sf does?

Because the initramfs that is being booted does not match the installed kernel modules that are needed to identify your root partition; the modules are not loaded and so the partition cannot be found.
