I can't boot the 4.4.0-146-generic kernel because of a kernel panic. I'm running 16.04.6 on an Intel Core i7-7500U CPU @ 2.70GHz × 4. See image below:

  • You can try booting the previous kernel version on Grub's Advanced Options submenu. Let us know if that works ok. – WinEunuuchs2Unix May 13 '19 at 01:18
  • @WinEunuuchs2Unix, yes that worked fine and [this solution](https://askubuntu.com/questions/41930/kernel-panic-not-syncing-vfs-unable-to-mount-root-fs-on-unknown-block0-0) already solve it. – luilver May 14 '19 at 19:30

Try to boot your Linux from the live CD/DVD, into the recovery mode prompt, then check your root fs, e.g.

fsck /dev/your_drive

Note: Add -y to fix any errors automatically.

Or:

chroot /mnt/sysimage
fsck -y /dev/mapper/dom0_root

The usual cause can be:

  • Broken grub config.
  • Root partition not flagged as bootable.
  • Bad installation (initramfs lacks or uses modules of another kernel version).
  • Bad RAM, try replacing. See: Random Kernel Panic on boot - not syncing.

You can try to fix your Grub record by:

  1. Mount your LXLE /boot partition (for instance at /mnt/boot).
  2. Install Grub bootloader by: grub-install --boot-directory=/mnt/boot /dev/sdX
  3. Then run: grub-mkconfig -o /mnt/boot/grub/grub.cfg.
  4. Optionally, if it fails to detect your other system, edit grub.cfg file manually.
