    deepin 15.5 - amd 64 - kernel 4.14
    deepin 15.5 - amd 64 - kernel 4.14  - recovery mode

    deepin 15.5 - amd 64 - kernel 4.9
    deepin 15.5 - amd 64 - kernel 4.9 - recovery mode

    try this:
    1.find the file:/boot/grub/grub.cfg.
    then copy some codes in this file:

    it's behind the codes like this:
    1. submenu 'Advanced options for Deepin 15.5 GNU/Linux' ......
    Copy the Code


    2.paste the code in this file :/etc/grub.d/40_custom
    like this:

    3. type in command:sudo update-grub
    4.find the file:/etc/default/grub
    and change fourth line:
    GRUB_DEFAULT="0"
    to:GRUB_DEFAULT="3"


    5.type in command:sudo update-grub

    after these these steps the computer were supposed to boot  the kernel 4.9 by default

    sudo apt-get remove linux-image-4.14.0-deepin2-amd64
    Simply remove the newer and not working command with the command above.
    Then it will set the older version as default automatically.
    I had a similar problem with the new kernel version on my laptop and that fixed it.

    With Nvidia drivers, and KMS mode enabled, is impossible to boot in last kernel, but, re-installing them, without KMS, makes it possible. I don't know if you guys, use Nvidia propietary drivers.

    My laptop only has integrated Intel HD Graphics and no special graphics card so that's definitely not the problem.
    I also tried to deactivate the proprietary intel-microcode but that didn't solve it.
    Downgrading to the older kernel was the only solution which worked for me.
